Well my gauges dont work(they go crazy) fuel gauge always show alittle over empty or 1/4 full, Temperature goes past the H, Fuel pressure goes high. My father said when he got the car around 6yrs they worked fine. What do you guys think it is?

-Regulator?
-Printed circuit?
-Gauge touching metal(if this was the case would the gauges even move?)
-Ground?(where do i look)
-Gauge?

Alright what do you guys think is the culprit? where to start?

thanks in advance

 

Start by checking the regulator. Your test probe should flash.

 

Im sorry to sound dumb but the cluster has to be connected right to check the regulator right

 

Sounds like the $30 P.O.S. regulator to me (I wish there was a better alternative). I am not an electrician, but I believe that you need to have the cluster connected. If you have a ohms meter use that to check the regulator. If my memory serves me correctly, the 12 volts coming from the battery should be reduced to 5 ohms after going through the regulator. Do a google search about the subject and you'll find some good articles.

There is an alternative, build your own solid state one. Only costs about $5-$10 and will last the life of the car. There are plenty of how-tos on the net, just search.

 

I also recommend the electronic instrument cluster regulator. We made one. You can build your own or buy this one on Ebay.

Good one tx65coupe> I was actually looking at the father and son site that you recommended yesterday morning and saw their solid state cluster regulator. I am trying to decide if I should build it my self or buy the one off ebay.

 

I bought that one off ebay. It's made by Ivan, a member of this forum (ic237). PM him if you have any questions.

i already bought a voltage regulator from Napa, i should of ordered 1 of those of ebay...On the other hand when installing the new circuit and regulator do i have to disconnect the battery or do anything prior to connecting the Gauge cluster?

 

I went through a few of those replacement stock type ones and none of them worked right. The original one works better than any of them did.
