charging of battery

Postby Vern Groves » Thu Jul 15, 2010 3:46 pm



I just recently purchased a '86 Gold Wing 1200 INterstate. The battery checks out pretty good and yet the battery went dead yesterday. What is my next step or two which I need to take to find the source of the problem? - Thanks, Vern

Assuming the battery is good (pull it out of the bike, charge it, and let it sit there disconnected for a day, to make sure it maintains its charge), the next step is to pull the fuses out, then start putting them back in one by one to see which one causes the drain to occur.

There may not be a current drain - it might not be charging. First thing is to check all the electrical connections in the charging circuit. Then I'd check the stator and the regulator/rectifier.

How do I test a stator and a rectifyer? And if it is one or the other, is the only fix to buy a new one? Someone told me that you can do like an external alternator (like a car) on this. Are they crazy or am I? - Verb

oops! I hit the wrong key - the name is Vern, not Verb. One is an action word.

Here are my discoveries. The stator is putting out plenty of volts. Now it must be the rectifyer or the relay. Where are they located and what is the way to get there (I"m learning about 'nothing is easy' on a Gold Wing). Remember, it is an '86 Interstate with all the fairing and bags and all.

Easiest way to check the charging circuit is to put a Digital Volt Meter directly on the pos and neg battery terminals. Should get close to the following:

Engine off key off 12.6+ v a fully charged battery should be as high as 12.8+ v
Engine at idle key on 13.2 to 13.5 v
engine at 2500 to 3000 rpm 14.2 v

If you get these voltages then your charging circuit is fine. If you have a dead battery then do as others have suggested and check for battery drain.

Can't talk to the '86 Interstate - on the '84 Aspencade it's under the false tank...

You are correct...it is under the false tank and a new one goes to the dance of just shy of $200. Oh well - greatly appreciate all the input I've been getting. You all are great.

I bought a new OEM unit on Ebay for $129.95 a couple of months ago. Just make sure to test the old one before you buy a new one. It's a simple continuity check at the connector and it's described in the manual. That's the first thing you should buy!
There are also aftermarket units out there for about $100.
