It seems a bit odd to use a analog and rather unstable reference as a filament bulb for charging when the engine is controlled by a computer.westendguzzi wrote: ↑Sun Jun 20, 2021 9:20 amThe charge indicator lamp is a current limiting device to provide small power supply to the charging circuit prior to start up. So best stick with a filament lamp.
Interesting to note that in the model rail world, they use a filament lamp in circuits to minimise power consumption in the event of derailment/dead short. Hmmm.
Anybody who happens to know the wattage of the lamp?
It seems like the neutral lamp also needs to be a filament type to activate the relay. I'll do some calculations and find a fitting resistance.
I connected a small RPM-meter yesterday and got i running, now i just need to modify it.
