Is there a way i can check my generator charge rate without taking it to the auto sparky.We know that the generator has a bearing issue,but instead of
replacing it,if it is charging correctly then we will do the bearings and nothing else.But if it is not we will do a rebuilt on it,eg bushes,Instead
of spending money i don't have to get a new one.
So yeah if know of any way to hook a voltmeter up to the gen and check if it is charging right,that would be great.
cheers guys

anyone?
umm i have a volt meter in the dash and when it's charging i read 13.5+
it's not charging at idle so it's like 12.7 something
but if it doesn't charge u might want to look at the regulator under the back seat aswell
good luck
so its not charging at idle? so it only charges when you are driving it? how the hell am i spose to measure that if i don't have a voltmeter gauge in
my dash.
get someone to control the accelorator and bring the rev range up
arr i see lol,so what should it be? around 13.5+ when at high rev and 12.7 something when at idle.Where do i read that at the battery or at the generator?
Correct charge voltage is 14.6 for a lead acid car battery, but anywhere over the already mentioned 13.5 is a good place to start. Voltage is only part of the story but all you can check with a voltmeter. Mind you you could check the voltage at the generator ie before the regulator, it should be 15- 15.7V, and you can see the condition of the brushes through the holes in the gen body. If the spring clips are disapearing into the brush holder they are well worn, there should be about6-8mm of brush protruding out of the holder, meaning you have plenty of brush life left.
at the genny or at the battery thats upto u hold the revs up around 2500 -3000

sorry matt

so.....
At gen points there should be=15.7volts

bump please
At the gen you want the meter between D+ and earth.
so D+ is on the gen right? and do you use the earth on the gen or just find an earth?
http://www.nls.net/mp/volks/htm/gen.htm
like that?
Yep like that. Earth......on gen or anywhere on clean metal....ASSUMING the gen earth and engine grounds are good, it's all the same.
mate i just did the test recommended on that site.with d+ and ground hooked up at idle was around 22.2 at high rev shot up to 48-50.
and the battery went to 14 like they said.That sounds good doesn't it?
Ahhh yes , just reread that site and saw that that high voltage reading as the D+ is disconnected, yes all good. If you dont disconnect it you'll only see high 15's by memory, it is stamped on the gen body how much voltage it's capable of.
yeah cool so the gen should be in good nick then ay? um my car only breaks down when it gets hot,could it be the coil?
That's a hard one, could be coil, fuel pump, fuel tank or line blockage or tappets to name the first things to check for.
its gets hot,starts loosing power ,and after a nurse home stops.
should i post a new topic,maybe someone might know.
The new post bit is up to you, but still think any of the above problems could be the cause, you can go through them one by one to prove each system, fuel electrics etc.
yeah that is what i am doing at the moment process of elimination.thanks
