Charging problem?

[brad1968]

I'm new here, i just joined and i have some questions. I have a 1978 GS750E. Bought it about a week ago and now im having some charging issues. I unhooked the terminals and used a multi meter to discover that there was only 5 and a half volt coming to the battery. What part or parts are not functioning properly?

Thank you,
Brad

Greetings and Salutations!!

Hi Mr. brad1968,

Most of your questions will be answered in the following links. It sounds like you need to start by reading The Stator Papers and use the troubleshooting guide. Clean every electrical connection and ground on the entire wiring harness, start with a known good battery, and follow the troubleshooting procedures to determine if you have a bad stator or regulator/rectifier unit. Let's begin...

I just stopped by to welcome you to the forum in my own, special way.

If the stuff in red means you disconnected the R/R (or battery), ran the bike, and attempted to measure the voltage at the R/R, dont do that.

It doesn't tell you anything, and can damage the R/R.

Brad,

Welcome to the GSR.

Good that you have a multimeter.

Measure the battery voltage with everything connected. Measure it with engine off, and with engine running at mid-rpm (like 4K). Is a tutorial on BassCliff BIkeCliff webpage about this.

BUt, yah, sounds like you have a charging problem.

The stator papers are very detailed and have you check lots of things. THe big test is the stator open circuit test (that one you do do with things disconnected, the stator disconnected). All these test are to determine if bad connections, or bad stator, or bad R/R.

WHere, in general, are you located?
