Re: IML: 1968 Check Gauges light

Hi List,

I have the car in the shop right now doing the front end, new brake lines and back springs. I'll be getting it back some time  at the end of next week so I'll check all that when I get back.

Then we can take it from there. Thank for all the info guys.

The ammeter is not linked to the warning lamp, and the brake system uses the other warning lamp. (I love that there are but three indicator lamps on this dash including the high-beams, and no turn signal indicators!) Even if your oil pressure gauge doesn't read properly (due to a gauge malfunction or just age), odds are good that the sender on the engine block is working properly and letting you know the oil pressure's a little low.

Or the sending unit on the engine is in fact losing its mojo... start by replacing that (it's readily available at NAPA or even some Chrysler dealers... you want the dual-pole type since you have both a gauge and a lamp). Then let us know and we'll go from there!
