M600 voltage question

[jerry]

output of regulator should be 14,3 v anthing above is getting dodgy anything lower is fine so long as its above 13.6v a good battery should sit at about 12.7v or more but its ithe amps output that denotes bad one ...

Along with properly checking the battery capacity, I’d do an earth leakage test to make sure you have no residual current drain in the circuit.

If the above don’t show anything untoward then personally I would go back through the connections and also get a meter to check out the Alternator and RR measurements.

Thanks Flip, I really appreciate your tips and advice. Sadly I'm a bit rubbish when it comes to electrics, so I wouldn't have the first clue how to do much of the above!

Have you got the original reg/rec on it?

Pretty sure I “borrowed” it for my 900 when that one when t*ts up, seem to recall when fitted to the 900 it showed over voltage hence I took it off and fitted an Electrex part.

Speaking personally as a true Luddite I steer clear of voltmeters and oil pressures gages on bikes as it only leads to stress. Old school, if the paint is being destroyed by acid from the battery breather or the engine is getting noisier I investigate otherwise ignorance is bliss.

Unfortunately, as these bikes get older coupled with a fairly weak electrical system to begin with, it is almost unavoidable in order to provide reliable long term ownership.

A circuit diagram and a DVM should be a friend in your toolbox unless you’ve got deep pockets to put a circa twenty year old bike into a shop for repairs when things go wrong- I would make sure you have recovery as well given the Law of Sod will mean a breakdown will likely happen on a wet dark night.

I think Lars means on the dash rather than the in toolbox?
