Guest Posted February 12, 2004 Share Posted February 12, 2004 1972 buick Lesabre starter problem...Old starter bearing went out screamed when starting. New starter bought and installed. Got in started car, fired right up, drove around block everything normal. Put in park turned off key...Car still running..Pulled coil wire to stop engine. Could the wiring be wrong? 3 lugs 1st marked 'r...Center post from battery...3rd marked 's'. when started it starts..no solenoid engaged after start. but keeps running. Wiring or igintion switch or tumbler set? which one first? any suggestions would be great... bayareareptiles@netzero.net Link to comment Share on other sites More sharing options...
rocketraider Posted February 12, 2004 Share Posted February 12, 2004 Did you replace the solenoid too? It may be bad. Wiring should be: Battery (+) cable to the large center post. Yellow wire to the coil on the "R" terminal. Purple wire from the ignition switch on the "S" terminal. Make sure none of the wires touch each other at the starter post or are pinched together in the wiring harness near the starter. GM and their wire routing <img src="http://www.aaca.org/ubbthreads/images/graemlins/crazy.gif" alt="" />...Next thing I'd check would be the ignition switch, but if it was working right before and started this mess after installing the new starter, that tells me there's something amiss with the new starter/solenoid.

JohnD1956 Posted February 14, 2004 Share Posted February 14, 2004 Most likely cause is that one of the small wires at the starter is actually laying across the top of the other one. This probably happened when you reached up to tighten the nut on the wire, and the entire wire turned with the nut. Just check to see if they are crossed, and straighten them out.

Guest Posted February 16, 2004 Share Posted February 16, 2004 Thanks for your help everyone...The part guys wanted to sell me ignition and tumbler set but I was with most of you, it must of been the starter, the part store didn't want to take the new one back claiming I was crazy..Finally they tested it and it wouldn't turn, so they got two seperate 12 volt supplies to tap 2 seperate lugs..Welding 101..Got new starter and solenoid, car runs perfect...by the way the contact lugs inside the solenoid were reversed so the one with the leaf contact was shorting to the center post. Thanks Again! Link to comment Share on other sites More sharing options...
