Question about Cars & Trucks
Do you have a volt meter ? How to voltage drop test starter motor circuit Here is a site for wiring diagram http://www.bbbind.com/free_tsb.html Enter your vehicle info.Year, make , model , an engine size. Then under system click on engine , then under sub system click on charging system (starter system is also under that ) Then click the search button , then click on the blue link . You can issolate the starter circuit at the starter relay in the under hood fuse box , to see which side of the circuit is bad , control or the load (starter) side . If you pull the relay out of the fuse/relay box an look on the bottom you will see four numbers 86, 85 & 30 ,87 .If you were to take a piece of 12 gage wire an jump where 30 & 87 plug into the fuse / relay box . And if the starter spins the engine over you just eliminated the starter , battery cables , ground circuit as not being the problem . This would indicate that something on the control side was bad , Park neutral safety switch , ignition switch . But before replacing parts some electrical testing should be done . Hope this helps an if you have an questions let us know .
