altenator gw 1100 1981

I have a 1981 wing and the altenator is always low until I get out on the open road and the revs are higher it goes to 14 amp. Other than that is low and I worry about running battery down. Is this normal...thanks guys Vern

at idle 12v"s is normal, at 3,000 rpms 13.5 about right..but it also depends on how many lights or draws you have on the circuit and how far away the meter is from the battery..and how clean all the connections are. Issues can be any of those AND the regulator not just the stator itself. Have yoiu checked the yellow wire connector for burn/melting???

No not yet. How can I test. I have a voltage meter. I am out and about now and will check back. Thanks so, so much.

It is possible the connector between the stator and regulator / rectifier is corroded. It is also possible some other electrical contact(s) aren't as clean and "positive" as they can be. A thorough cleaning of battery terminals, and inspection of the stator / regulator connections (personally, I'd remove the connector and solder the wires together) and possibly some other inspections and cleaning are in order.

I do not have a voltage meter on mine. I look at the intensity of the headlight at start up and as I'm riding to give me the only indication I have of how well my charging system is working. It isn't very scientific, but my headlight burns as bright at idle as it does at road speeds, so I figure voltage is pretty near where it needs to be at idle ...

Hard-wiring or bypassing the plug in connectors seems to help in most cases and definitely can't hurt in providing stable electrical supply to the R/R... I guess I could ask what RPM your engine is set to at idle... I think the book calls for 1000 +- 50 rpms or so. Mine is slightly higher than that.
I am wrong as often as I am right concerning what is wrong with someone else' motorcycle without having seen the machine in person. Guessing with limited information, as to the source of the trouble, is sketchy at best.

Put the meter on the battery terminals..and test at various RPM's. If the 3 yellow wire connector just to the front of the battery is brown/burnt/melted you must cut it out and either solder the wires back together, order doesn't matter, or put separate connectors on them and re-attach but leave them loose of each other helps to dissapate the heat. Even if it's not burnt replace it.
