7V Regulator

Here is another option for a 7V regulator that is working for me. I have about 300 miles on this now so far with no problems.

It is from Dimension Engineering. I just velcroed it in place.
I purchased their breakout board to mount it on. Makes wiring it in easier.

OK, i need an explanation...

This replaced the 7 volt gauge regulator on my GL1000. The fuel and temperature gauges use 7 VDC instead of 12VDC to insure accuracy and stability. That way the gauges always have a constant voltage instead of fluctuating with battery voltage. Otherwise the gauges would typically drop at idle when the stator voltage dropped.

Uses three wires just like the original. Just have to wire it in directly instead of using the original plug. Just has three wires, battery voltage, ground and the output to the gauges.

This is mounted behind the left door/panel of the fake tank.

Here is a picture of it in place. Note the high tech Velcro mount.

What is the picture in the upper right showing the regulator mounted on a board next to something?

Top left, first post is the finished package. Top right is the transistor they use, then the transistor on the board with the other components required to adjust the voltage.

Middle left and right are different views of the finished package.

Bottom left is a "breakout" board with a (very funky) 3-pole socket for the transistor. Bottom right is the package in the socket for a finished product that's easy to wire.

It's all a little "un-engineered" for me, but I like to pot stuff and would probably find a way to water-cool it or something!

keeping it simple keeps the cost down, the regulator is only $15

It looks like a tough little unit.

going to have to try that on mine finicky temp readings and gas gauge is way too inconsistant

It's been installed for awhile now and is still working. Noticed you are from Tyler Texas, I used to live there back in the late 70's. Is it still called the Rose Capital?

Oh yeah still the Rose Capital it has gotten alot bigger but there are some great rides along this part of Texas.

Satisfied it worked, I gutted the old regulator and used epoxy putty to fill and hold things together. Installed back in stock place.

I had the parts, but bought at Radio Shack, about $3.00

How did you get the old epoxy out? I tried that and destroyed the case.
That old epoxy is hard!

Drill press, drill press vice, gloves and a lot of patience.
