fuel/water temp wiring

[Mud&Rox]

recently rewired my 68 IIA. now trying to get the water and fuel to work. could someone enlighten me to how? the bible shows a voltage stabalizer?

Yes, there is a voltage stabilizer in the circuit. RN has them available. Just wire them per the wiring diagram in the service manual and they should work fine.

If you still have the voltage stabilizer you probably don't need a new one if you don't have one you'll need one. It drops the 12 volts to 10 volts because it allowed for more accurate gauges, at the time (1968), the originals were adjustable, so if you have more then 10 VDC coming out or less then 10 VDC you can dial it in to be closer to 10 VDC. Your fuel/water temp gauges won't work on 12 VDC. Well at least not accurately.

tried the 12v and nuthing. so i dug the old one out i think is it about 1 1/4 by 3/4 and have 2 female and 2 male spades?

That should be it. Apply battery voltage and test the output voltage before you install it to make sure it's working. Output should be close to 10 - 10.5 VDC.

And if you're using a digital multimeter expect to see wild readings between 4-13 volts... which presumably average out to a nominal 10v.

Kind regards, Josh

Though like Nium said, the guages will work without one - they'll just read high all the time. If yours aren't reading at all, I'd suspect a fault somewhere else.
