I got my engine all hooked up in my 92 300d finally and realized I didn't hook up the small power connector to the distrubition block. I went to crank it and it wasn't cranking at all but it had power to the starter. And it fried the glow plug relay and it went up in smoke. WHat else do you think that I could have shorted out or destroyed? If I destroyed some major computer that will affect starting this car again I'm sending the car to the junkyard. I've had enough of it.

It would help to know which wire and which distribution block. I wouldn't expect anything to go up in smoke unless you had something miswired somewhere, the glow plug relay only deals with power and ground, even if some little signal wire weren't hooked up, it shouldn't matter to the GP relay.

There's no computer involved in starting the car either. The IP is mechanical and will run even if the EDS computer dies or the OVP trips out or fails. If the engine will crank and you have fuel and compression, it should start and run, even if all other electronics are toasted.

The small ring terminal from the positive terminal harness. One large ring terminal goes to the starter, the other small one goes to the power distribution box that is mounted on the driver side wheel well with all the other crap up there. I don't understand how I could have the glow plugs hooked up backwards because there's only two connectors and a ring terminal on it. When I swapped the motors around, I plugged in the relay right away and had that at least labeled.

Not sure if I'm reading you correct but with regard to the starter there is a large ring on a large wire, goes to the stud on the solenoid, then there is a small ring that goes to the small stud also on the solenoid. The small is the control that activates the solenoid which simultaneously energizes the solenoid to operate causing the starter gear to thrust forward and engage the ring gear and closes the high current contacts to energize the starter motor to rotate.

Any chance you mis-reconnected the wiring and that's why the starter doesn't turn when the key is operated?

The smoking relay doesn't make logical sense either, assumimg you left the glow plug harness attached when you pulled the engine you would have only needed to plug the 6 circuit connector into place on the relay, or did you swap the harness and the relay from the donor car?

So both ring terminals small and large connect to the stud on the starter? I'm not sure why the glow plug relay fried myself. Everything seems to be connected right. I left the grounds from the harness connected on the motor I swapped in and plugged everything back in the relay from the "new" motor and didn't use the old harness.. It was hacked together by PO that damaged the wiring.

Perhaps the glow plug relay stuck on?

Has to be something with me not having that wiring hooked up properly. After all, I'm glad to read what I have.. Don't think I'll junk it now after 3 months of off and on work to the car

I'm going to connect the small ring terminal to the starter if that's how it goes and see. I made the mistake of not taking pictures and labeling things when I did this swap because I assumed I'd remember 3 months later.

Checked it. I will try what you said in the message. I did hook it up maybe not tight enough. I don't have the small ring terminal hooked up, probably why it won't start. Still clueless why my relay smoked up.

IF the ground strap was not transmitting electricity as it should..
then that power , if any route back to the other side of the battery existed, would all try to go through some smaller wire....
and would burn it up in short order.. no pun intended....

Yes, you need a good bond at the ground strap. Funny things happen if you don't. I left it off in the process of a 240D engine swap and the clock grounded through the speedo cable. It was a puzzle, why was it warm to the touch?

So you might clean the the connection surfaces with a file to make sure you have shiny metal on both. One of the surfaces might have oxidized/rusted over while disconnected.

The large go on the large, and small on the small. There is as many as three larger wires (terminals), and one separate smaller wire (terminal).

BUT...

GP Relay is FUSE-LESS
IT's ELECTRONIC !
(ONLY 124.128 s and one W140 have these GP RELAYS!)
If the Relay senses an Electrical problem It won't work until the Problem is Fixed!

ALSO If the smaller 4 Gauge Feed to the Power Distribution Block is left
Un-Connected NOTHING ELSE ON THE CHASSIS GETS POWER!
EXCEPTING THE ACTUAL STARTER MOTOR (NOT THE "BENDIX")

If You've "Fried" your GP Relay It's because Zomeone Rewired the Chassis
AS IT WAS NOT Supplied to Customers with that Ability!

Unfortunately, I Believe Rollguy's Quotation of your earlier explanation
in the reply directly above is the SOURCE of your Dismay!
