93 S-10 electrical problem

[lite39]

Hello,
I have a problem with my truck (I love my chevy.... )

I have had 2 alternators installed and a new battery( it was six yrs old).
The reason for changing the alternator in the first place was the bearing seized and was forced to change it.

After having this done the electrical system has gone haywire.

The problem is :

1. Starts fine then the gauge for charging will go up and down and battery indicator on dash will light up then go out. The truck will have sit over night and once it is warmed up(heater on since it is winter) The problem seems to go away for about a day then early mornings it will do it again.

This morning I noticed my speedometer was increasing while in park and reving engine to see if the battery would charge. I am wondering if it maybe the printed circuit behind the instrument cluster.

I have gone to dealership and a great mechanic that are stumped.

I have since found small water droplets under the carpet on my fire wall inside truck under the dash. I am wondering if this could be a problem.( windshield not properly sealed)

I have no experience in troubleshooting this type of problem.

Would a poor ground cause such behaviour?

I also have a trailer light kit and am going to remove it later today.


Thank you in advance for you help.

lite39 you problem is you need to have your cluster repaired. call a speedo shop in your area and they will tell you the samething and look into spending atleast 200 for the repair
