"Click" when trying to start, problem and solution
From reading here I was pretty convinced it was the starter relay/solenoid on the fender, so I went and bought one today at Advance Auto for $9 or so, and while I was at it I picked up some new battery terminals, the "quick release" type and a battery terminal cleaner.
I took the old terminals off and found there was a lot of rust on the strands of the negative wires and a lot of rust and corrosion on the positive wires. I used WD40 & a rag to clean them off, seemed to work pretty well, don't know what you're supposed to use. Put the quick release terminals on and the truck cranked just fine, problem solved I belive.
BTW, the quick release terminals are very cool, they have a lever on the bolt head. With the lever up you tighten the thumbscrew on the other end of the bolt, then press the lever down and that makes it tighten another turn or so, locking it onto the post. These will be really handy since so many projects start with taking the negative battery terminal off, and it's always been a PITA because the only tool I can get a bite on that that nut with is pliers, which always dinged it and the terminal up.
Just my 2 cents.
Guess you could keep WD40, silicone, or something on there to help with the rusting problem, but you'd have to stay on it.
Yeah my cables are looking a little tired too, they should probably go.



. I'll buy those things and see how it works. thanks
