Hey guys new here and relatively new to ramchargers. First off I'll give some specifics of my issue I'm attempting to diagnose then I'll get into the build so yall have a better understanding. First off I drove my truck to work at the dealership last week and at lunch got in turned it over and click, didn't turn over. I pulled the starter and found the starter nose that sits in the bell housing had sheared off. Also this was a old school starter from the late 70s more on that later. I replaced the starter with a ultima reman (cheaped out) it trys to turn the motor over just boggs down motor turns maybe quarter turn and stops when attempting to start. I checked battery voltage and cranking amps (new optima battery btw) which was 12.4V and 1040 amps respectively. Next I checked for power at the starter with a DMM which was battery voltage. I've inspected the battery wiring all grounds and can't find an issue. I pulled the starter and bench tested it and it worked fine. I turned the motor over by hand 4 times to insure its not locked up this one has me stumped. Now for the build I have a late 80s 360 bored 60 over, mild flat tappet cam, mated to a 97 cummins NV4500 5 speed manual, rpm performer intake, hooker headers, holley sniper fuel injection and holly duel sync distributor holley coil and ignition box. Also the truck no longer has the starter relay on the fender, plug is there though. Been driving the truck for two months since installing engine without it having a starting issue. The power wire running from the starter to the battery like I said is good however there is a small wire that comes off the positive battery terminal that runs to a connector along with the small wire from the starter. The connector wiring runs into the fender somewhere I'm assuming that is for the ignition switch I could be completely wrong. Trying to find material on this is hard plus the previous owners of the truck have done some let's say strange things with the wiring I have found previously on unrelated things, trying to work out stock from joe bobs back yard job can be difficult at times LMAO. But seriously I'm wondering if this new starter has the same torque as the old school starter because the old one never had a issue turning the motor over. I cant find specs on the new or old one anywhere. Im close to ordering a dynomax starter but before i spend 400 bucks i would like to eliminate all other options. So if anyone can steer me in the right direction I would greatly appreciate it!
