Has anybody put an ignition warning light on a BEC. I assume I need a supply from the ignition and one from the regulator but could do with
details.
Thanks Gordon
wouldn't the Oil Pressure light function as an ignition light anyway?
Good thinking.
Id got myself thinking that when I turned the ingition on there would be no indication, but as you point out there will.
I guess the only thing it wont do is tell you that the battery is being charged.
Gordon
wouldnt the battery warning light come on as well? or havent you included one?!
Joel
Thats the bit that seams to be missing on bike electrics, but Ive got more than enough wires to sort out at present so I think Ill just go with the
oil light for now and look at putting an ignition/charge light on in the future.
Gordon
It's a fair cop Gordon - I hadn't considered that - I guess I'll need another circuit that lights something up if the battery volts is
less than (say) 13V, easy enough to do, I can use the shift lights.
I was still thinking in terms of a conventional alternator...

Could you give a rough idea on how you'd rig up this warning light - my knowledge of electronics is very imited. Many thanks

Isdweb,
zener, pot, transistor, resistor and LED. Chose the transistor connection (common emitter/common base) so the temp. coeff of the zener & the
transistor cancel each other out (under dash temps exceed 100c in summer) Get a mate who does electronics to work out the details & debug!
I'm doing a digidash for Gordon so very easy & cheap to include as an afterthought!
Cheers

Many thanks Bob
I'll get my Idiot's Guide to Electronics book out............
