i made a costem gauge cluster for my 91 camaro rs and i dont know how to hook up the volt meter dose any one know how...

any help will be appreciated....

Thanks.....

 

Just hook up the power source for the meter to any 12 volt hot when the engine is running source. I spliced mine into the stock harness, using the factory wire for the factory volt gauge to power my Autometer.

Another option is to use the terminal specifically for this purpose on the back of the alternator.

 

thanks, TKOPerformance

i going to go try it right now

i have the older alt. so there is only two wires red and white
can i hook it up to the white wire to get a reading if it dose not work ?

thanks....

 

You'd be better off connecting to the 12 volt keyed plug in the fuse box. Then you don't need to run the wire through the engine compartment.

The old style 12SI and 10SI alsternators have a red wire and brown (sometimes white or other colors) wire that control the stator and the rectifier respectively. The white wire should be a reference signal to the rectifier assembly, so you wouldn't want to tap something off of this wire that will produce a current draw, even if it is a relatively small one. The result could be overcharging the system and burning up the alternator.

Use the 12 volt keyed tap. You can use a spade connector to plug into it, or they often sell a pigtail for it at parts stores. There are at least two taps, and one is 12 volt constant. Use a test light if you are unsure. Plugging in to the 12 volt constant will result in eroneous readings.

 

thanks i got it i hooked up one to a hot 12 votl while it was on and the other one to a good ground dan it works

thanks for all the help, TKOPerformance

 

No problem, good luck with it!
