I f you have the old style Battery 1 - Battery2 - Both - switch you can blow out the alternator diodes by switching while the engine is running. These diodes restrict the charging of the battery to DC. Before electricity can reach the battery, it must pass through the alternator's diodes, which are the most common cause of alternator failure. The diodes pass the electric current on to the positive battery cable, which eventually leads to the battery itself. However, the failure of the diodes to function properly will essentially disrupt this circuit. Jerry

Looking for suggestions of diagnosis / solutions. See below: thanks The alternator belt was somewhat loose but I tightened it and no luck on charging. Tested terminals on back of alternator and reading was same before and after tightening... About 35 volts. About to start this morning by checking / cleaning battery terminals and other connections from alternator back. Hoping this could be the issue because as I previously posted my starter has been giving me the clicks. I have the faint glow on the Charging indicator lamp at the engine panel too. I have a heart interface "incharge " alternator regulator. Any other suggestions?
