1984 KLR600 Electrical gremlins

Well now we have new issues with the son's 600. The battery won't stay charged and it doesn't want to run with a dead battery. So I would assume this is a battery type ignition. I plan on checking the regulator tonight when I get off work but was hoping to get some direction from anyone that has played with these older KLR's. We did replace the old battery because it looked sulphated so it has a new battery.

I have found this to be very valuable when trouble shooting electrical on the bike. Also an electrician brother helps.

Its probably the voltage regulator/rectifier at fault but could also be corroded connector plugs, if you can get the engine running test the voltage at the battery should be 13.5v ish , above 14.5v reg/rec at fault, check all the earth points too, I have a 1988 600 and found a few corroded plug pins. hope this helps and good luck !

Well he made it thru yesterday with no issue's. We cleaned a few grounds when we did the valves on Monday so he next step will probably be to clean all the grounds and check the connecters for corrosion.
