there are three terminals on my voltage limiter.2 terminals are spliced together.the third is a stand alone.is the stand alone terminal 12v in. and the two shared terminals go to gauges.i have a pic of it all wired together if someone can make since of it. i think it may be wired up wrong. also the is a capisitor looking thing that goes to one of the terminals

i kinda wanted to get this wrapped up by the weekend. i found a replacement regulator,but it has 2 terminals and mounts different.

you didn't specify car or type of gauges, so generically, there are 3 prongs on the instrument vr.

1 end is attached to the outside case and is ground.
the middle has a capacitor pinned into the board with it and is 12 volts from the plug.

the third supplies the gauges with 5 volts.

so if you have any of the 2 wired together you either are supplying 12 volts to the gauges, or are running a dead short.

the ralley type should work the same, but I am unfamilar with how they are hooked into the gauges.

What Andrew said, I dont think 2 of the terminals are supposed to be spliced together & I'm wondering why someone had done that. Any possibility you can get the correct one?

its a factory splice.what i mean is 2 of the spaids are put together with one rivit,the other spaid is by itself. i have pics if that helps.i just need to send them to you from my phone.

i guess i should mention its a 73 challenger with rally gauges. i.e tach/clock,ect

yeah, you are going to have to show a pic. doesnt make sense.

here are some dash vr links though.

does it look like this one?

Yrs andrewh that's what I got

so the 2 pin is just 12 volt power.
the other single pin is 5 volts out.
ground is the case, there is a cut out on one side that it bolts to the ground.

part way down you can see he has lables on it wired up.

well i just bought a 2 terminal solid state ivr3. my question now is what terminal gets the 12 v and which goes to gauges as 5v.one of the terminal has an adjustment screw next to it.is that the 5v terminal?

i forgot to mention andrew the 2 terminal is the updated version of the 3 terminal.i no longer need the capaciter according to instructions.now i need to figure out what terminal goes where

didn't this help?
