Hi All, I have a 1970 Buick Skylark, and at no point in the start-up sequence do any of the idiot lights come on in some sort of test phase. I was wondering if that was by design in 1970, or if there is a problem with my wiring. Does anybody have any knowledge on this matter? Thanks, Thomas
Put the key in the and turn the ignition on, to the "Run" position. The Oil and Generator lights should be on. When you crank the engine to start, the Hot light should light. Yours doesn't do that? Either the bulbs are burned out, or there is a wiring problem. Get yourself a Buick Chassis Manual. There are diagnostics in the Instrument Panel Chapter. https://www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=1970+Buick+Chassis+Manual&_sacat=0
Hey Guys, Thanks for the quick responses. I actually just replaced every bulb in the dash cluster, so that should not be the problem. The Brake light comes on if the combination valve is stuck, or if the parking brake is on, but not as a start-up sequence. It looks like a wiring problem from the guy before, as the car has never had those bulbs lit. I think it may be because he put in an aftermarket oil pressure, temperature, and voltage gauge, and diverted some of the wiring there?
Yes, wiring. Pretty common problem on old cars with many owners. Do you have a Chassis Manual? Only if the PB is on, or you have a hydraulic problem.
