Regulator unit
fogrider:
I re-set the gaps as stated in the Haynes manual (all I've got ). Cold. I tested it, made adjustments bit by bit and it now complies ( fairly well ) with the settings Haynes describe. Good enough for now, but I would like one of the combined units said to replace the 2 items.
Not sure which one or if there are wiring issues.
At least I'm rolling again and not destroying another battery.
Thanks all....
Bryanj:
Stick with what you have, the combined units have a high failure rate and really dont like bad connectors, voltage spikes and reverse connections.

Personally I would stick with the original arrangement that Honda designed it seems to work pretty well. Only time I can see the need to change it is if you are going away from lead/acid type batteries.

Just abstain from gel batteries. Some can become damaged when voltage gets over 14,3 V. AGM should be no problem, but to enjoy its full potential, they have to be charged at 14,8 V, which leads to the alternator having to work harder, which in theory results in less performance and a somewhat higher fuel consumption.
My standard Yuasa is 61/2 years old now and still works fine. Your choice.

Thanks for the above, I shall stick with the good old mechanical regulator. Interesting note about 14.8v to charge AGM batteries.
My Optimate never really got it to the expected 12.7 / 13v limit but a charge on my ancient constant current charger at around 14.7v it came up to 12.9 and has stayed recovered.
You live and learn !
