7V dash regulator location?

Post by oldmopars »



I am looking for the 7V voltage regulator on a 89 GL1500. Anyone know where this thing is at and what it looks like? Any chance you have a picture of it?

The 1500 does not have a 7 volt regulator.
The fuel and temp gauges are direct fed 12 volts.

Here's a more inclusive diagram.
What problem are you having?

Well, no problem yet. What I am doing is making a GL1200 into a naked bike, but it had a digital dash, I want to use the Speedo, temp and fuel gauge off the GL1500 I have and I thought that it also needed a 7V regulator. But if it was 12V, then that makes my life easier. I will have to play with it and see if the gauge will read good enough for my needs. Then I get to make a new housing for it. \
Thank you

Cool.Even some of the 1200's didn't use the 7volt regulator.It may be the one your working on.Not sure without a bit more info about the 1200 if the resistance of the sensors is close enough for plug and play.

By the way.If your 1500 cluster has a good LCD display..carefully remove it and offer it for sale.There kinda rare and expensive.

Only the 1984 GL1200 Standard, with analog gauges (the same gauges as on the previous year GL1100) uses a 7 volt regulator. All other 1200's drive the sensors directly from the digital panel. The digital panel itself will have some sort of regulator in it to drive the gauges and sensors, it has to, or else the temp/fuel would rise and fall with the engine RPM. Whether or not it runs the sensors at 7v or not, I don't know - I suspect it might, or they would have to use different sensors for the digital panel GL1200's.

The GL1500 voltage is stable from the regulator in the alternator, so having a secondary regulator to stabilize the voltage for the analog sensors is not a requirement.

Any chance you can help with the wires? I have 6 wires to sort out.I am down to 1 wire I am just not 100% sure on and I can't see it on the diagram you posted.
Here is what I think I know:
Solid green--dash light ground
lt green/black--dash light +
Yellow/White--fuel sender
Green/lt blue--Temp sender
Black/Brown--switched power
And this one I am not sure of
Green/Black--Ground??
I think it is a ground as it goes to both gauges just like the Brown/Black. Just want to make sure.

Yes.green/black is ground.
I also found some information.You would need a ohm meter to check the temp sending unit resistance to see if it meets the specs to operate the analog gauge.

Gl1200 digital gauge use

Gl1500 analog gauge use

The analog gauges use a different sensor that the digital one.

Great, thank you. This will help a lot.

This will be a lot easier than what I am doing for work right now. I am creating a document to connect a Water Jet pump from one brand of machine to a table of a completely different brand. I am having to describe in a document, then add pictures so that a tech 1000 miles away can go and follow my instruction and wire the whole think up. It involves analog to digital signal, relays, E-Stop circuits and 8 different wiring diagrams from 2 different companies.
Makes working on the bike seem easy.
