Troubleshoot ignition start
Posted by: fred bagnall ()
Date: April 04, 2021 09:01AM

I went to Advance Auto to get some Nicorp line to redo my fuel lines in my engine bay. I turned the ignition switch on and both idiot lights lit up and then nothing. I went to try it again and now have no lights. I still have power up front to the switch. As soon as I turn the ignition switch on the red hot wire goes dead. Did my ignition switch short out? Also I have courtesy lights in my van. Even though there is power up front the courtesy lights are not lighting. I have tried to jump from the red hot to purple on back of switch and when I touch red to purple, the red wire loses power. Strange, it all worked fine when I arrived here.

check battery terminals and wire connections for looseness or corrosion

Battery terminals are clean and tight. Power up front at switch.

There is a loose connection somewhere that is letting power to the front but will not carry the amps needed to make anything happen. If this is your van don't they have the famous connector by the battery that fails like this.

Full power at both sides of connector. Power at back if ignition switch. Tried jumping back of switch power to solenoid ,power at switch goes away when jumped to solenoid??

Fred if you are certain both battery cable terminals/posts are clean and tight and ground connection to frame and over to engine is clean then look at pos cable end at solenoid.

Try this first: 12 gauge jumper wire between pos battery post and the purple wire going to starter. Make sure you are NOT in gear please. If power is lost again the next place is at starter end of cable.

How about telling us which vehicle this is? Makes a difference in the troubleshooting process.

Ken he stated in first post 'courtesy lights in my van'. I am presuming it is his FC. I hope presuming is correct. ggg

The reason I suggested jump using purple wire to starter is that I typically would start at the rear because more connections etc. Plus I have seen numerous times that jumping voltage to starter shows a bad battery or cable connection and I am near the battery to see/hear it snap as connection fails.

So I took a short piece of wire and jumped from hot battery post to the solenoid connector at firewall. The solenoid turned slowly. The battery connection was clean and tight. I crawled under the van and found my battery connection was loose. I installed a new heavy lock washer and retightened everything and it started right up. I initially was stumped because I had power on both sides of all wire connections. I had power up front, but what I didn't have was a good connection for full voltage to run through. Lesson learned on my part. THANKS for the help and suggestions everyone.

You are correct. I should say "amps or current ". I didn't think clearly that having the main battery connection loose on the solenoid would still let me have some power up front, but not enough to complete the starting circuit.thumbs upthumbs up
