we used the factory wire harness on the new motor and everything hooked up the same, the only things we are missing right now would be things like the oil temp and water temp. but just trying to turn the motor over for maybe 30 sec, the coil is getting kinda hot as is the possitve mattery cable

Hello,
Thank you for allowing me to assist you, my name is ***** ***** I will be happy to assist you with your concern today.
I do not have the engine info so I do not know if this is fuel injected or carbureted.
Please pull the distributor cap and while cranking check if the dist rotor is turning, if so please confirm that engine was set at tdc when distributor installed and if so check if getting trigger pulse to coil from the ignition module. You can test your trigger pulse via a test light on the neg of the ignition coil while cranking the light should pulse, if not then your missing the trigger pulse.
If fuel injected I would need to know as there are other things in play.
Thank you!
- Joe
