Just put a new booster and Mastercyl on my 70 Challenger 440RT. While I was at it, I masked off the firewall and did some touchup with my airbrush. Put everything back together and now I cant get the starter relay to kick in. When short out across the terminals, it will engage. Now,I did disconnect and reconnect the bulkhead wiring and moved a lot ot stuff back and forth, but I thought I had everythomg reconnected OK. I must have messed something up either under the dash or elsewhere. Can u guys give me a troubleshooting plan to go thru so I can find out what I did. Electrical issues are my downfall, so the simpler the better. I did try a spare relay that I had.....no luck. Battery is good. Thanks and happy
