Starting 2001 502MPI on Stand
 

Ive looked at all the wiring diagrams for this motor. I need to start this motor in order to get this sale completed. Does anyone have an easy reference for hooking up only what wires i need to make it run. I dont need gauges or anything like that. Thanks guys.

Battery Positive to the Solenoid on the starter
Battery Negitive to block
run a #10 wire from the positive of the battery to the red/pur side of the solenoid on the motor ....(this is the hot wire from the ignition..ie run ...you'll have to lift this wire to shut the motor off ....

jump a positive from the battery to the yel/red small terminal on the motor solenoid to start .....

I think this is right .....be careful....m

I got er. I appreciate the help. On this motor. + from battery to starter, ground to bell housing. On the mercruiser plug on the motor. Hook 5(purple) and 6(red with purple stripe) together, number 7(red/yellow) wire touch it to 5 & 6 and bazinga!

I cant take credit. I studied the diagrams for a bit. Eric from EB marine gave me call and told me to tie 5 and 6 together.

Please don't do this on an engine building stand but use something low to the ground.

put your motor on a engine dolly and put 4+4s cross ways under the dolly and afix the 4+4 to the dolly.this way the engine will not flip over in the floor when your running thr motor.

Its on a pallet bolted down.

Now that is an ugly visual!!!

no chit,could you imangine that big hunk of cast iron getting away from you.better have steel toe boots on.lollol

why ?? other than oil pressure and run period thats all you be able to tell....

Would you buy an engine you couldn't hear run?

Depends on who I was buying it from. I sold my spare engine last summer with out starting it. :drink:

I just wanted the guy to be comfortable with what he was getting. Only right to do.

my point it it could be knocking and you would never hear it on a stand with open exhaust

how about for a 500hp carb engine?
