I'm sure it wouldn't actually need to be as low a resistance as the bulb. Jim

On 29 June 2011 16:45, Mark Miles <[email protected]> wrote: To get around that issue with your charge circuit you just need to connect a 39ohm resistor in parallel with the charge warning led. That will approximate the resistance of the bulb (about 38ohms). You should then find that the alternator gets sufficient seed voltage to operate as it would with the bulb but will retain the functionality of the charge warning light.

It would be better to connect it to an ignition circuit if you have to. I've always found that even without the warning light connected there is enough residual magnetism in the alternator for it to self excite about about 3000rpm and then work fine after that. My 2+2 does that because i changed the warning light to an LED but it's not really a problem. Maybe not the case on a brand new alternator though.

Also leaving it connected when the alternator is not turning causes the coils to heat up as well as being a constant drain on the battery. On a new alternator the heating is unlikely to do any damage but on a well used one it could accelerate failure.

But, the alternator must be outputting the battery voltage on that pin when it's running to put the alternator warning light out. There can't be any volts dropped across the bulb or the bulb would glow. Jim From: Mark Miles Sent: Wednesday, June 29, 2011 3:34 PM To: [email protected] Subject: Re: [Quantum Owners] Re: Alternator trouble I would be a little concerned at connecting the alternator to the +side of the battery. The seed current for the alternator starts as 12v BUT the bulb acts as a resistor which drops the voltage to a much lower value. My concern would be damaging the exciter coils in the alternator.
