alternator still overcharging GSXR1100 86
Having an issue with my charging system (GSXR1100 1986.
Even after modification done as described in picture coming from OldSkoolSuzuki
and a new regulator installed,type as picture
I still read 16-18 V DC over the battery when engine is running on 3000 RPM and above
I had the same numbers with the stock regulator, so no difference using the new one
Is next step to find a new or used alternator or are there other things to check prior to replace the alternator completely?
