Hello All,
I'm new to this forum.
I also have been bitten by the disease and am the owner of a few old british bikes one
of which is an 850 mk 2 Commando. I have made little changes from the origional
with the exception of a smaller bore master cylinder, an oil pressure gauge and a battery monitor.
I also have fitted a GPS and use the trip log to give me an indication when I need to fuel up, and a
speed indication for those nasty speed traps.
The battery monitor is described below and fits neatly inside the headlight shell it is about an inch square circuit board
and the led goes where the useless asimilator lamp was.
If I can figure how to attach photos I will do so else I can PM them
Came across a neat little circuit that uses a bi coloured LED and very
few components. It has an adjustment to set a trigger point. I set the
point to be just above 12.5 Volts and the led glows (red) below this
level , above this level it glows (green).
It fits where the asimilator lamp is and gives me an indication of
ignition on (red) and when the engine is started it glows (green) if
the charging circuit is working or stays (red) if you have a problem.
You could set the trigger point lower if you wish but I wanted the led
to be (red) when the engine was not running even on a good state of
charge battery, the charging circuit will alway bump the battery up a
bit. I actually started the engine and set it to just be green at idle.
The circuit can be used to monitor voltages anywhere between 9 and 30
volts.
If anyone is interested I can post the circuit.
Regards
Peter R
