My first post about a slow cranking starter was resolved by replacing a battery thanks to this forum suggestion to replace the battery first. My second post question is about the charging system on 1982 xs400sj. I replaced the 35w/50w sealed headlight with a headlight with a h4 bulb style, with a 50w/60w bulb. I have noticed when I check the charging voltage with a meter the voltage is 13.5-14.5 volts around 3000 rpms and when i rev to around 4000-5000 rpms the meter will not read any voltage. Is this cause by the voltage regulator stopping the system from overcharging?
