Hello all, I have finally gotten my 1980 MGB running and the temperature gauge and fuel gauge does not work. After a little research, it seems that the instrument panel voltage regulator/stabilizer is the culprit. I found an old one in a bag of parts, as I bought this car as a basket case, with parts everywhere! I can't seem to find anyplace behind the dash, as some of the posts have described.

Does anyone have a picture of this Regulator/Stabilizer IN PLACE, that they could share? I know what it looks like, but since mine has been unplugged, I need to know where and what color the wires are. I do have the schematic/wiring diagram and it doesn't seem to be on it!! Thanks in advance!

Art, it's a hard picture to take. THe little bugger goes way up under the drivers side. Location don't matter a whole lot, as long as the wires will reach. Make sure it is well grounded, and just put a screw in holding it.

But chances are the critter should be replaced. They got really flakey as they got old.

New solid state units for under $20.

77 MGB - Four tone paint -Pertronix - hood props - cheap tires - new springs all around - mixture of poly and rubber bushings- fuzzy seatcovers - stereo out of old F150 pickup -runs flawlessly and drives nice.

78 MGB - Done right by a good PO, and I only bought it. Tell Jim how nice it is. But I did put in a Datsun 5 speed.

53 TD Mark II - a work in progress.

This car is now very nearly completely done. Sure to find something else, but not now.........

The stabilizer is up and behind the left side of the steering column. I'm not sure if the wires are both green or one is green/white.
This is on a '74, yours may be different.

Early 1974 MGB with OD, SU HIF's, 72 spoke chrome WW's, Schlemmer Pertronix, DuBois fuel pump, Limey's relays, Gerry's column kit.

Thanks much for the replies, and the picture is EXACTLY what I needed!!! I know mine is shot as it was in two pieces! I also know how to make a solid state unit. It's actually quite simple, now to find those pesky wires!

One more picture by Bruiserman shows the Voltage stabilizer (circle on the right) with a green wire and a light green/green wire. Also shown is the Inertia switch (circle on the left) to cut off the power to the fuel pump should you have crash. The button on the top of this switch needs to be pushed down to let power go to the pump. In a crash it pops up and cuts off the power.
