what's wrong with my wiring in my bus?
for those who dont know me, i am working on a rather modified 76 kombi ad have just begun getting stuck into the electrics.
ok, so far as i can see i have wired the car back to its original setup, but at the moment i have 3 problems:
- there is no difference in light output from my headlights between parkers and lights and there is no light coming from the taillights
- my blinkers do not come on. when i have the emergency switch fully wired and the blinker lever on i get strange noises from the flasher unit and a
light from the switch. when i remove 2 of the wires from the emergency switch , pull it on and shift the blinker lever in 1 direction i get 1 blinker
working (front and rear)(this last thing has stopped happening since i got a new flasher unit)
- when i started my wipers werent wired properly and i could only get them to operate when the lever was in the central position. when i wired it
properly i only got movement in the bottom position only. after a bit of sparking and blown fuses i decided the problem was the motor, switched to my
spare, got 1 kick out of it then nothing. cant even get the wires to spark anymore, but cant find any blown fuses up front.
any suggestions?

I am not trying to be funny, but you definitley need an auto elec or someone with that kind of knowledge and test equipment to go 'hands-on'

Hmm.... wiring is just one of those things we can't fix if we can't see.

if an auto-elec saw the state of wiring i do not think i could pay them enough. the car had the wiring modified when the camper top and conversion
went in, then again (very poorly) when the first subi engine went in, and i cant find enough space to run all of the wiring now, especially since i
have added an alarm and central locking of my own (at least i have gotten these to work!)
not to mention i dont have the $$$ to get someone in, so will have to battle on on my own. just didnt know if anyone had had similar problems to any
of mine and if so how they had fixed them.

Hey ive got a simple solution 4 u that will work out cheaper then an electrician, Buy a complete wiring loom, relays,switches, etc then add your
custom parts for the alarm etc from your custom loom you have now, just make sure u write down what wires are for what when you modify it, I had
similar problems in my beetle, time is what u need, good luck |

Check that you don't have corrosion at the following places:
- the end caps of the fuses. My reverse lights didn't work b/c of this (fuse is in the engine bay)
- the globes and their holders. I still have occasional trouble with rear lights from this cause.
- spade connectors onto globe holders
- earth connections
If that doesn't work, you could always come around and check out the wiring on my 76 kombi! I'm in Box Hill.

thanks mns, hadnt thought to check corrosion, the sad thing is i stripped all of the wires off and started from scratch last week, copying the spare
that i had, along with the orig wiring diagram. will check down the back tho, maybe i disturbed something when i fitted the new taillight housings.

I've had fun redoing a lot of wiring in my '75 camper that was screwed up by previous owners.
The first thing to do is sort out if things are running off the correct fuses: get a piece of A4, draw a line vertically down the middle, then draw
horizontal rows to divide it up into 12 rows. In the left column, write the things that are supposed to run off each fuse (the fuses are numbered 1
to 12 when looking at the fusebox left to right). Now you put in the right column the things that actually run of each fuse: pull the fuses out one
at a time and see what stops working!
Once you've got an idea of what should work from each fuse, it's a question of finding bad connections (most likely) and incorrect wiring (less
likely) by testing systematically with a multimeter. You'll eventually get it all sorted.
Hints:
- Solder stuff to make it stronger (e.g. where you crimp a spade fitting onto a wire).
- Use only electrical solder, not plumber's solder (which is corrosive and will eventually cause the wires to fall apart).
- Use insulation tape on everything (e.g. wrap it around spade joins) as it prevents short-circuits and also reduces the evils of vibration.
- Always use wire that is rated to take enough current (e.g. if you have a 16A fuse in a circuit, it's a good idea to use wire that can take 20A).
This is so that if a short occurs, the fuse will blow before the wire catches fire.
- Make sure EVERYTHING is fused!
