What sort of issues do I expect with 6v system?
Can anyone give me some opinions please. Is it worth upgrading to 12v?

weak lights, cant fit a decent sound system. The bulbs are getting exy too.
If you want to use the car everyday I would change to 12v.

the only good thing about 6v is the ability to allow others to see you spear off the road at night. you wouldnt be able to see diddily squat at night.
so unless your anal about retaining originality, i would suggest upgrading. it is not hard. my bus was converted and everything operates fine.

My old '62 could only run the radio when nothing else was on, including the brake lights, wipers, etc. The volume of the radio would halve or
dissapear. Also operating the wipers would halve the intensity of the headlights etc... it's worth changing to 12V just for the safety aspect.

when you are sliding around a corner at night with both outside wheels on the gravel hoping you don't hit the telegraph pole that was dimly
illuminated at the last second when you realised that there is actually a sharp corner in front of you, you will wish you had upgraded to 12V.
(hows that for a long sentence)
btw. ask me how i know. 
my car also had issues starting which wasn't helped by being 6V.
unless you have a 36hp it isn't hard or very expensive.

My '60 KG coupe is 12V. The only issue I have the wiper motor. It's still 6V with a "Queen Mother" resistor in front of it. It
works fine at 1st then gets faster & faster till it's hard to switch off because the parking-stop cam gets over-ridden by the momentum of the
wipers going at warp speed!
Yes- a12V 36hp is possible but expensive- you need a Porsche 356 gen. Mine cost me $250 3 years ago!!

I'mn interested in converting my 54 bug to 12V as well...
Do you rekon you could write out a project sheet or something including costs for myself and others that may be interested? I think i like having
headlights and high beams that actually illuminate instead of depending on the car in front's brake lights to show you where the road is!

oval tofu. i never got around to converting my car to 12V... i kinda hit a guard rail before i got the chance... it was at night, but it was because i
was an idiot not because of the lights.
the "how i know" was i found myself in that prediciment one night. (different night...).
i have converted a 63 from 6 to 12V though.
if you want to convert your oval to 12V it shouldn't be that hard... if it has a 36hp motor, not the cheapest, but not that hard.
you'll need:
a 12V generator (if you have a 36hp then you will need to find a 6V size generator in 12V... a la porsche 356... or get a 6V gen rewound to 12V.)
plus a matching regulator.
for 40hp-1600 motors, a 12V generator stand and gen hold down strap.
a 12V battery... try to get one with recessed covered terminals (less chance of toasting the car). you'll need to modify the standard battery
strap for the bigger battery. on my 63 i made up a little bit with wire... it wasn't the prettiest but worked well (will be redone properly resto
time)
a 12V coil.
(i can't remember if condensers are voltage sensitive.... anyone)
all new bulbs. don't forget the dash lights and interior light etc.
as for the horn, i fitted a 12V item i had about. the 6V one might survive ???? or change up to the dixieland airhorns you've always wanted. hehe
prob the biggest stress is the wipers. there is a thread in the mods section re fitting a 12V wiper motor. you can also fit something to drop the
voltage. don't know exactly what... (electrical stuff is NOT my strong point + my 63 was a straight wiper motor swap.)
starter motor... if it is in ok nick it should last alright. i've heard it said you should change the solenoid to a 12V one but i have ridden in
cars that had used a standard 6V starter motor for years.
semaphores... never done it. have heard oppinions both ways on this to.
if you are running blinkers i think you heed a new flasher unit.
for later motors with electric chokes you'll need to think about the choke element... if you hook a 6V one up to 12V it glows, emits black smoke,
then doesn't work anymore... hehe.
another thing to think of is ovals have screw on connectors... if you fit a later wiper motor, or motor + switch, you'll have to crimp some spade
connectors on the ends of a few wires. (plus add another wire or two if going to 2 speed wipers... oh the luxury!)
i don't know if you need to change the ampage of the fuse you use... don't think so but can't remember if did or not. but while you
are at it, you may aswell replace the fuses... clean the terminals while you are at it. it does make a difference.
if you have the cash. it is worth getting everything ready and sorted before you pull the car off the road. ie have the generator sorted tested
waiting to be fitted. get a second wiper mech and mod it before hand. have all the bulbs, crimps etc etc. if poss have another car handy to pick up
any parts you find you need and try and do it at a time when you can get to a parts shop/ auto electricion (sp), get the bits you need and fit them
before you have to use the car. (if it's a dayly driver anyway).
something you might want to check is the fot of the top pulley onto your new gen. i've seen a friend get caught with this prob before. after the
gen is fitted and in check it's alignment with the bottem pulley. if they are not in line you will keep throwing or chewing up/breaking
fanbelts.
all in all not to hard really. if everything is sorted before hand it doesn't take that long either. well a few hours or so.
hope this helps. is you have more Q's i'll try and help.
henry.

That info is gold! As Darrryl Kerrigan once said That's going straigh in the pool room! I've read the thread on the wiper motors :o
but nothing ventured nothing gained eh? I had a 64 that was 12V and the person that did the conversion (a bit dodgy) had an oldskool coiled wire
resistor running through a headlight/deashlight dimmer switch. So in effect, you could have more than just 2 speeds on your wipers. It wouldn't
bo that hard to integrate it into your dash so it still looks stock but you'll have something like 30 wiper speeds... now thats luxury!
So let clarify: I've got a 6V 40HP engine and therefore generator. A larger 12V generator and stand will still align with the fan housing
correctly? how much would you expect to pay for a reco-ed 12V gen and reg?
I'm sure i'll have plenny more questions for you when i actually do it... so you just wait for my bombardment of stoopid Q's later
aii?

sorry oval i have no idea about the prices. the gen will align at the correct height etc, it is just the foward backwards positioning of the fan in
the shroud and the pulley that might need a little tinkering.
when you get the fan shroud with the gen fitted sitting back on the motor. do the shroud screws up first. then spin the generator to listen for any
scraping of the fan and shroud before you tighten up the gen strap. you might want to check again after the strap is tightened up.
then it's time to check the pulley alignment. if you can pick up a few shims from someone that has stripped a few cars and have them on hand just
in case.
there are a few things with fan width. i'll check it out and get back to you on this.

hi oval. just wandered up the yard to the shed'o'death and checked it out (and managed to only get one hand greasy! hehe)
i think you will need to get the 12V gen mount plates (that fit into the fanshroud), as the different generators mount onto the plate slighty
differently. when i did mine i just dropped a complete second hand 12V gen/fan etc into the shroud.
i checked fan etc clearence today by dropping a complete 12V gen/fan etc into an early round fanshroud and a 12/1300 fresh air shroud and there was no
rubbing etc.
the pulley size on the 12V was the same size as that on a 6V (ex 1300sp) gen i have (aprox 110mm across the outside lip) but i checked an 36hp (ex
oval) 6V gen and it had a smaller pulley.
if you are getting the gen rebuild it might be easier to get them to fit/swap the fan over as if needs a big socket (36?mm) plus you might need some
special tools to hold the gen shaft while tightening the nut (??? never done it).
hope this helps. if you have more Q's keep asking.
henry.
oh another thought. if you are using the headlight switch for the wiper motor you might want to fit a thingy... i think it's called a triack...
so that the power running through the switch is only low ampage (the triack uses a message signal from the switch to control the amount of power
getting from the source to the wiper motor). this is as the voltage adjuster in the light switch is only designed for running the dash lights and a
wiper motor would draw alot more current. ie might burn the adjuster but out. plus you will prob need to find an oval headlight switch (so it has the
right mounts for your car)(you know how they mount with a screw under the dash).
h.

Raf
I suspose it boils down to what sort of car you have and year model or if its restored or modified....
My resto cars are both 6 Volt and dont have much problems except for not being driven enough.
where as my daily driver Orange Smoothie went straight to 12 V without any questions.... although i am still using a 6volt starter n flywheel soon
to be converted to 12V type.

So Dave what hp is Orange Smoothie?
I'm going to have one final attempt to find a working 6 volt generator for Bel before I totally give up. Beginning to realise that keeping a
daily driver 36hp, 6 volt is not really practical as decent parts are getting harder to find. Lights are not a problem, I use the 6 volt heligen ones
and seem good enough, better than the birthday candles she used to have as globes
OK have heard stuff about 12 volt melting semaphores, is this a myth or real? Did I hear right?
Sorry to ad my 2 c but this is an question I'm beginning to ask as well |

If you change to wrong size 12v bulbs (wider ones) they can melt the lenses. (ask me how I know) Better to stick to 6 volt bulbs with voltage reducer
for semaphores. The little 6volt semaphore bulbs are getting hard to find now too.

12v
had a 12v conversion done to the 56 oval and no problems since been done. used a 6v gen rewinded in 12v, only prob it doesn't hold at idle so it
doesn't charge (on idle only) 12v reg. changed all the bulbs,12v battery as far as semaphore concerned just hooked up a resistance of .75 ohms
and they work fine ,horn is still 6v... what a hear balst ... at least people can hear it ,lol .. wiper motor is quite a problem as i haven't
found any later models that would fit so put a resistance as well.... works fine.... and got a kickass stereo in it now too...
i think that the exercise came up to a toal of $ 600 ... but i had to get two gen. rewinded as one of them was already done in 12v and died on me. |

So conversion was done by someone else, or was this cost made up of a combination of yours and others work?
My mind is beginning to tick over about this one seriously |

while we're sorta on the topic of semaphores, i managed to install mine today. They trouble is, even though the globes work (yes! i have 6V two
semaphore globes! mine mine mine! all mine!) they are hooked upto the flasshing unit and therefore, the voltage turns on and off with the blinking to
the semaphore's armature. (which also isn't enough to actually raise the things to horizontal... only if i manually move it up to the
horizontal level will it hold there for the second the blinker lights up)
anyone help this poor lil battler who cant even start his car yet?

oval tofu, before you gonna indicate, drop a gear down to get the revs up and get more voltage through and your semaphores you go up and sit nicely,
2nd gear should be good usually... |
