A 79 will not have the fender junction box....you will need to jump the starter itself with a large screw driver....just touch the small screw to the large stud on the solenoid...I wonder if your ground strap on the transmission bell housing has came loose...

This is why I am glad there are W123 guys on the forum.
BTW I used insulated needle nose pliers to jump the wires.

Can you use the screwdriver from on top or do you need to be under the car?
I would hate to see her having to crawl under the car each time she wants to start it while she is in the OBX!

okay...I have been out there all this time and took off all the wires from the solenoid to check...nothing frayed, connections looked good...spent forever looking for a junction box, but the closest I came was a small wire off the solenoid that ran to the glow plug black box thingy on the fender. So, im going to put it all back, and YES! joy of joys, I can reach the whole contraption from above!!! For I, too, was concerned about climbing under my beloved but much on my shit list right now Benz, all the way to f-ing ocracoke! So.....the small screw and large stud (sounds kind of interesting)...they are both the ones on the solenoid right? The small scew has the small wire, and the large stud would be the nut with the 3 other larger wires attatched? I will be back in to confirm info after I crawl back under car to reassemble...love you guys! We might make it yet!

okay, I have it all back together, and am awaiting instruction on exact screws/studs to bridge with screwdriver....also, I guess I have the car in neutral with the key on for this?
while under the car, I saw a small wire with one of those round ends that goes under a screw/nut hanging down unattatched to anything...it comes out of the lower firewall right by transmission housing. is this the ground strap?

Mercedes colors their ground wires brown. I am suspecting that this wire is from the original NSS (Neutral Safety Switch) and is no longer needed.

The ground strap would be a thick flat braided wire with no covering going from the transmission to the body

TO start the car, turn the key to "on" let the glow plugs cycle then jump the small wire to the large wire using that screwdriver. Make sure that it has a plastic handle, that you do not touch the metal shaft of the driver while doing this, especially if you are leaning on the metal body of the car!

I just got back fro Kill Devil Hills! I love it down there!
Good Luck!

Thank you so, so much! My friends own two houses on Ocracoke, and they let me take the kids down once a year because they know I couldn't afford to rent a place...my kids are so looking forward to it, I couldn't stand to tell them we couldn't go! The sea turtles will be hatching out when we r there and they r excited to see that. I am just hoping that the starter did not completely take a dump on me, and that it gets us down and back. Then I can have it changed out (or the solenoid, whichever it is). I will try it first thing in the morning...dark out there now and no lights and I finally got all the grime off from laying in the gravel and stuff earlier.

Thanks to all of you so much for helping me...you guys r the bomb. Will update in the morn!

Hmm, 4 kids and a manual transmission? I see a solution.

Turn key on for two glow cycles, shifter in second gear and the call of "who wants ice cream?" oughta provide the energy needed.

I imagine the wire you see hanging down is for the kickdown solenoid of the automatic trans....sounds like someone didn't do a great job of a trans swap.....it seems you have a replacement glow plug relay....on this year car, the glow plug relay is under the dash, not on the firewall....wonder if this is causing an issue? The ground strap is usually under the drivers side and runs from the body directly to the transmission bell housing....sounds like besides the manual swap, this car has a lot of issues and neglect...
