NO Start issue.
Well Mom called and said her truck will not start so went over there and took a reading on the battery it was 11.0VDC so tried jumpers and manage to get 13.5 on to it still no start so took jumpers off and checked battery again 12.0 so looked at battery it was 6 years old so that has to be it so went and bought another battery installed it nothing still. Crawled under it jumper from POS battery post to the solenoid and it engages the starter and turns over so some where in between the starter and the ignition switch I have lost my 12VCD telling the starter to engage. HELP I have worked on a new 2003 F-150 in ten years.
I meant to ask on the older truck they had a starter solenoid on the wall is the round thing next to the battery have anything to do with the starting it the original 2003 one and how do you check it??

The other thing the guy should have done though was to check for voltage on that small pressed-on wire to the right, with the key at Start. That's what powers the solenoid to cause those two big wires to be connected. Pop the wire off of the terminal, stick a meter lead or a test light in the plug and turn the key to Start. If the light doesn't light or there's no voltage shown there's a problem with the ignition switch or the wiring. Solenoid (starter relay) is highly likely though.
Good video though.
