Question about 1983 Suzuki Tempter GR 650
Start off with brand new battery at beginning of season .lasts for about 2 months and then wont start unless I bump start or boost it.seeking advice on where to start to trace this problem.I have very little knowledge about this bike,but want to try to fix it myself.Ive heard of a part called a regulator/rectifier,but dont know what it looks like or where it is located or how to check if its faulty. Any advice will be greatly appreciated. thank you very much.
The only easy way is for you to buy the service manual - it is pretty hard to tell you how to service your regulator if you don't know what it is...
And it is - or at least something in the charging circuit.
Early Suzukis had consistent charging problems, resulting in run-down batteries, short battery life, hard starting and frequent stator and regulator/rectifier replacement. Some of the problem is due to poor quantity or corroded electrical connectors, some to a poor ground to the regulator/rectifier and some just poor quality components or design. Keeping the connectors on the three stator wires clean and by running a heavy ground wire directly from the negative terminal of the battery to the regulator/rectifier mounting bolt will help.

I picked up a battery minder for mine. Harley Davidson (gasp!) brand, it hooks to battery terminals, and has a small socket that can be tucked between the seat and tank. Just plug it is when it is parked, an it will keep the battery in shape. It micro-cycles the battery when fully charged, even over winter.
