K100 battery/charging issues
My 1990 K100 will not put a charge on the battery. So far I've done the following:
1.After testing with meter at the battery and showing no charge above 12vs, I pulled the alternator and had it tested. I was told the alternator was good.
2. I've cleaned and checked all of the ground wires and connections to the battery and alternator.
3. Retested the battery.
I've had this charging issue since I have had the bike (less than a year) so there are no events that lead up to the failure that I can provide. Somebody had mentioned that the starter relay can somehow cut the charge to the battery? Any suggestions would be appreciated- I've already done a few searches and have found very little info regarding charging issues-
