7 Volt Regulator installation

Postby rstoops1 » Mon Jun 03, 2013 9:51 am



I have recently purchased a 1977 GL1000, the second one I've owned. The bike is in almost showroom condition, looks and runs like a new bike. The Temp and Fuel gauges are beginning to become intermittent and I assume I should install a 7 volt regulator. I'm not familiar with the gauge wiring and how the 7 volt regulator would be wired into the circuit. Anyone had to do this yet?

This is the second GL1000 I've owned and by far the best of the two. I also own a 2001 GL1800 which I dearly love.

Thanks in advance for your help,
**** Stoops

You don't need to install a 7-volt regulator, you already have one. It's a plug-in module, about 1" X 2" and is mounted in the left side of your shelter. Go to Honda here and look at #8 on this fiche. That's your 7-volt regulator. Open your left false tank cover and look for it. You'll find this module a little forward of center, mounted flush with the shelter and it has a white plastic connector going to it. (If you take your tool tray out and look to the left of the air box you'll see it protruding into the interior of the shelter.)

The last thing you need to do is to replace this unit. You say that the gauges are 'intermittent'. If that's the case, that's a classic sign of loose or corroded wiring or connectors. So, first, you need to check your wiring and make sure that all of your connections for this circuit are clean and tight. If, after doing that, there's no improvement, you can either pick up a used 7-volt regulator on eBay (Honda no longer sells them) or you can buy an aftermarket replacement.

In case you need a laugh, here's a NOS genuine Honda regulator on CMS for (only) $236.82. Hurry, there's only three left!

This is a classic sign of a failing 7 volt regulator. They rarely fail suddenly and outright, they become intermittent for a while, then just die.

We sell them here on our site: Replacement 7 volt regulator, and you're in luck - yours is among the easiest to replace. It's located in the electrical area underneath the "service door" on the left hand side of the false tank. Replacement is a plug-and-play task, should take you less than ten minutes.

Thanks for the help WingAdmin, I would never have found the regulator on my own. I wasn't able to find any info on this regulator in my Clymer's manual or in the wiring schematic. I intend to purchase one of your replacement regulators after I've rechecked all of the wiring. The GL1000 only had 12,379 miles on it when I bought it on May 3 of this year, but it had sat for 5 years. I have the bike running fine now, after running several tanks of gas loaded with carb cleaner. The best part of the purchase was I only paid $600.00 for this pristine bike.

I purchased the new 7 volt regulator and plugged it into the circuit. When I did this I discovered that the ground terminal was loose in the socket in the wiring harness. This isn't apparent when the socket is released from the regulator on the bike because everything seems tight when the socket is released. I don't know if this was the cause of my problem, but it may be something to check if anyone else has this problem with the gauges. I'm leaving the new regulator in place just because it works great now.

I purchased one of the 7 Volt regulator for here and it has helped with my temp gauge but my fuel gauge still isn't working right. My fuel gauge worked for about a week before it started to act up again. Do you think that it is the regulator or is it something with the fuel level switch. I don't want to tare apart my gas tank I will if I need to. I and using my trip odometer for now.

Problem could be in the sending unit, but first I'd check for a broken wire, loose connection, or a bad ground. Problem could also be with the gauge itself.

I checked the new regulator connections and the ones that I could get to that hook to the gauge and they are all tight. When I first replaced the regulator the gauge worked but it hadn't been working for about 2yrs so I don't know if it was damaged. Do you know how hard it is to pull the sending unit out of the gas tank?
