electrical issues

[airjake89]

do you guys know if there is a relay that would run the coolant gauge and gas level gauge my 88 ram was sitting for about a year changed the battery the gauges worked with the nearly dead battery but once i started it with the new battery the first time gauges dropped all the way truck runs and fuses are good

No relays in the sensors, but these trucks can get all kinds of gremlins in the electrics from bad grounds. Disconnect all the ground leads in the engine bay and give the terminals a good clean along with the ground lead bolts. Check you battery leads too. If you lost your gauges in one hit it would tend to indicate a single fault rather than a bunch of individual issues.
