Hello everyone,
It was bad this morning. I almost drained my battery getting it started. 1984 300SD. Lots of smoke. It was about 10 deg C and I was getting scared. I thought I would have to ride my motorcycle to work!
The weird thing is I just went out and started it right up,. the temp now is 16 deg C.
I took some OHM readings on the plugs on the 200k scale from the plug socket on the wheel well to a ground on the shock absorber:
1-21.3
2-29.3
3-21.2
4-.000
5-.000
Also, I have never seen my glow plug light come on but I'm sure at least some of them are working because I had some starting trouble before and I replaced plugs 4 & 5 and it cleared right up. they were reading 1.000 before I replaced them.
I thought it might be a burned out bulb but I just tested and swapped it with one that I know works and it still didn't light up. I checked all the fuses in the fuse box and they are all good.

I'm sorry if this has been addressed before. I checked the DIY section but it wasn't much help. I really need some help from you guys here I don't want to ride my motorcycle in this weather. That would really stink!

Danny
