I've recently replaced the voltage regulator on my TW125 and it seems the voltage is a bit high for the AGM 12V battery that's inside.
At the moment, I have north of 15V unloaded with just the full battery connected and 14,6-7V with the headlights on.
I suspect this is just due to production tolerances (it's probably a chinese-built regulator copy) but I'd like to keep my (new!) battery working and not gas it prematurely.
So I thought of putting a big power diode in the regulator to battery line but I'm afraid of frying it... Please note I didn't say I was putting a diode between the battery and the starter. The common wisdom is to never run a motorcycle without the battery : is it to keep a load on the regulator? smooth the output? not completely clear depending on where you ask... But in any case, I'm afraid of a regulator malfunction because of that.
Am I in the clear or is there something I'm missing?
