What did I fry...?

Trying to get the project running, 1965 Chevy C10... Took out the old worn out 305 and installed a fresher 327. The problem started when I tried to fire up the motor for the 1st. time. Turned the ignition switch and nothing... I had dash lights and other power, but the starter would not engage. I jumped under and started looking for problems. Made the mistake of my wrench touching the live power wire for the starter. Couple of small sparks and a few foul words. Went back to try again and now nothing. No lights on the dash, headlights, no power at all anywhere... I am hoping just a fuse somewhere and not something more serious. Any ideas where to look or what to check...? I looked at the fuse panel, but didn't see anything that looked blown. So, my problem went from a non-working starter, to no power to anything... Had the starter wired to the leg on the outside away from the block. I belive I need to move the smaller wire to the leg on the inside, toward the block...?

I don't know where the fusible links are on a '65, but on my '75 there is one at the starter end of the main power feed and one at the end where it connects to a junction on the firewall. On newer trucks they use a 14 gauge fusible link, which protects a 10 gauge power feed wire (usually an orange/red colored wire). The fusible link can burn out internally and the external damage may only look like bubbled insulation. The fusible end is replaceable, by splicing on a a fusible link you can buy at most any parts store (display card will call it a GM fusible link).

There are three terminals on the starter.
- The large lug is where the battery power connects, along with the main power feed wire, and the charge wire for the alternator (the starter lug is used as a power junction point). The fusible end of the OEM power feed and charge wires usually have a plastic bullet-like collar a few inches from the end.
- The R terminal is where you connect the full power wire for a points distributor. This provides full power to the points (no resistor) when cranking, to make it easier to start. If you have switched to HEI there will not be a wire on this terminal.
- The S terminal has a small wire that runs up to the ignition switch to activate the starter. It will not have the plastic end collar like the charge wires, and is usually a smaller gauge. I think the stock wire color is purple.

No fusible links on a 65....You answered your own question....The "S" wire goes on the terminal closest to the engine block.

If you are still running points, there is a wire that also goes from there up to the coil, so it has 12 volts while cranking.

Got it going... The wire that connects from the starter to the harness had what seemed like some sort of fusible link... I'm not sure if it was bad or or not. Didn't look correct, so I cut it out and soldered in a new eyelet and moved the wire from the "R" lug over to the "S" lug. Installed the power wire for the starter and connected the battery. Got out the test light and began checking things... Everything seemed to have power. So, I went and turned on the ignition key and everything worked... Beats me, but I guess that the wire from the starter to the harness had some sort of link or something that was shorted. Or, just moving the starter wire from the "R" terminal to the "S" terminal solved the problem.... A round of thanks to all that helped... I am truly appreciative....
