Voltage Regulator ajustment

Postby grandpa » Sat Aug 07, 2010 3:47 pm



I have just bought a 1978 GL1000 Interstate. But charging voltage is too low. App. 12 volt. Should be 13,7 volt.
Can some one tell me how I ajust it, if it can be ajusted and where is the regulator placed.

The bike was first driven in Crydon. Id no. GL 14005166

There is no adjustment..but check the yellow wire connection jsut forward of the battery box..it may be melted..cut wires solder together is the fix. Check stator for output..should be 60 on each leg..if not stator is going out. regulator coudl be bad as well..you test that too with a meter..you need a shop manual it has all the procedures to test. Checking and cleanign all connnections is a good idea too especially the grounds.

Hi RBGERSON
Thanks for the information. Wery helpfull. I checked the voltage on the battery with an external meter. 14 Volt at 3000 RPM That is OK. But the meter on the instrument panel showed only 11,5 Volt. So there is a problem. At the same time I found some lose connections and when I used the turn light to the left, some of the "side" lights went off, and when I used the turn lights to the right, some of the "side" light started flashing at the same frequenz as the turn light. So I think I have to check all the wiring and as you say the grounds are very importend.
But again thank your quick respond.

Sounds like the meter on the bike is bad. Check the voltage with your external meter as close to the bike meter as you can.

I am on a buiseness trip for the next 4 weeks, but all your input will be stored in my memory an when I get back home I will use them. So just keep on giving me input.

This is a great site, one of the best I have seen.

Note meters that are installed far from the battery lose V readings..I have to add 1.5 to mine to get accurate reading. To test this take meter out hook directly to battery and check reading..lower I bet!!! Anyway lenght of wire, connection and ground will all effect readings

Certainly a bad earth will make the meter read low and will cause all sorts of weird electrical gremlins.. Definately check the earth connections and if in doubt, undo them and clean them..
