What did I fry?

Hi everyone,

I have an MSD ignition box and the power wire runs along the radiator support to the positive terminal on the battery. I recently put in a new radiator and must of damaged that wire in some way. It shorted against the radiator support and cooked pretty good. There didn't seem to be any other damage so I replaced that wire but now there is no power to the starter when I turn the ignition key. all the lights work and when I turn the ignition key the radio and the ac blower work. I was able to jump the starter and the truck started right up and ran fine. Could I have some how fried the neutral safety switch? Thanks for any help.

Check the fusible link at the junction block on the fender

I checked the fusible link as suggested. its good. I have and extra neutral safety switch. I'm going to swap it out to see if it works. I don't really see how the short I had is connected to the neutral safety switch but its acting just like when I had a bad switch in the past. We'll see.

You can just unplug the neutral safety switch and use an alligator clip test wire to bypass it. Then see if it starts.

If you still have troubles I recommend posting a picture of how you have the MSD connected at the battery and what the battery terminal looks like.
