89 gl1500 loosing charge on battery even with comu fire alter

imported post

Hello forum. Having trouble keeping my battery fully charged even after installing a compu fire alternator. Battery was new last spring. It was discharged late last fall recharged and installed. I decide to also install the comu fire alternator. Lights and starting was relatively better, however. This week keep noticing the voltage display showing low charge. After stopping and trying to start, the battery clearing shows signs of lower charge. Starting is not as brisk as before. Any suggestions on how to go about checking the charge after the bike is started from the comu fire. Is there a voltage relay or something that is not allowing the alternator to charge the battery. Once the bike is started evreything is fine. The alternator is quite able to keep the bike going with all lights, radio and cb on.



I can continue to every 3-4months to pull the battery and charge on a bench but this seems really to defeat the purpose. I wonder if the discharge on the battery before the new atlernator will maybe never be correctable.
