I have a1988 1500GW, I have replaced the altenator and battery, and my alt light will start flashing off and on at times. I have checked the charging and it is good. When I turn on all the extra lights and turn signalthe alt light will flicker. Any idea what to do next??
PapaBear, if it is still doing the same thing even after an alternator change I would think it isn't the alternator malfunctioning.
If it (your problem) was caused by loose wires or loose connectors you would think it would happen even if all the lights weren't in operation.
Those 1500's have a rather low charging system output compaired to an automobile so there is a good chance you are just over-drawing on your alternator at all-lighs-on
& lower engine RPM's. If it (your problem)happens only at engine idle or low engine RPM I would suspectyou have more electrical load than alternator output.
It seems that a lot of people are installing after-market high output alternators on those 1500 Wings & they wouldn't do that if not needed.
I know that when I use my heated grips & electric vest my battery discharges at low speeds & on my other bikes with an alternator lightthe lightflickers off & on at low speeds.
You might want to check the charging voltage when the problem occurs & if the voltage is also low suspect too much electrical load for your present alternator.
