Ballast Resistor
Hi All,
When I turn the ignition on, my kombii starts but as soon as I stop turning it over it dies out.
I asked a guy and he told me my Ballast resitor has died. I have a starter coil that requires one, its an SU10R I think and it say resistor required
on it.
I guess my question is where is my ballast resistor? I have 2 wires running off the + on my starter coil which go to 1/ another coil (which I thought
was used to charge my aux battery) 2/ the back of the carby. Or should it be in the distributor or on the way to the distributor?
I figure its possible that I don't even have a Ballast resistor, if so my sarter will prob be burnt out right?
Any help will be much appreciated
Cheers
Milt

Ceramic ballast resistor in a type 2 ????
On vehicles with a ballast resistor-
The coil is rated at less than 12 volts...
so when You are turning the starter motor over, and the battery voltage is NOT 12 volts, You are still getting enough voltage for the coil....
Once the engine starts, the power goes thru the ballast resistor, which drops the voltage going to the coil otherwise the coil would probably overheat
and fail....
I haven't had much to do with the ballast resistors, but all the ones I've seen are white - about 4 inches long -
square in shape with the resistor wires going round it..
they are made from ceramic material....

Your ballast resistor should be located on the wire that connects to the + side of the coil. Ignore the ones going to the carbs or from the
starter.
Its a whitish creamic rectangular thingy about 12mm square and about 60mm long or so. It has a wire from the key attached to one end and the other end
goes to the coil +
They are usually attached to the coil bracket but can be found in a variety of places.
Trace the wire back that eventually goes back to the key. It should be there somwhere.
Avaliable from ANY car parts store.

It seems as though i dont have one then.
This is a problem then right?
Could my coil have died from not having one and then cause this problem on startup???

Hi
As a rule VWs never had a ballast resistor. What is probably happening is the ignition swith is failing to mantain contact during cranking. Look
closely at your igntion lights, they should remain on during cranking, if they dont a new ignition switch is needed.

Thats true but he is running a ballasted type coil.
But the idea of the key switch being dogey is certainly a good one.
