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.

I would recommend the following:

1. Check the voltage at the battery terminals (engine not
running). Note the voltage.

2. Check the voltage at the battery terminals (with engine
running). Note the voltage.

You should see 14 plus volts (with engine running) if the alternator is good.

If you have sufficient alternator output, then I would have the battery load tested. If you don't have a load tester, most auto parts stores can test it for you.

Are you using a Gel or AGM battery (maintenance free battery)?

If you are using a wet cell battery, the battery can't handle the CF (at least it is not recommended to use it with a CF).

I agree with DBohrer and the checks he recommends.

Another 2 cents:
Recently installed a Venco voltmeter. Was smart move, as I can now tellmy battery's & alternator's condition at a glance. Venco: http://www.vencowings.com They do landmark mailorder business and Jim & Sue are nice folks. Jim's very knowledgeable on Wings andworks only on them; from the '75 model on.
Don't forget to check ALL connections you can find in charging circuit. Found loose circuit connection meself last year[egg on face, LOL].And, even the main fuses can develop corrosion under both end screws[BT-DT].TTFN.....Old Tom
