1983 300D won't turnover in cold
It has not been that cold 45 hi/ 30 low. I have been pluging in the heater and it has worked until this morning. Glow plug light comes on and off but when I turn the key just a click and nothing. The engine does not do anything. It is not the battery and when the temp rises, it cranks fine. Could it still be the glow plugs? Please keep it simple I am new at this I am doing the reserch to get my husband to work on it.

It's not the glow plugs. If the starter is not cranking and the battery is good, it is possibly the starter or the solenoid (on the starter). It's unusual that it would act up at only 30F. Is this the first time its done this?

I started last week when the temp dropped. I started plugging it in and had no problem until this morning and it would do nothing until lunch when it cranked.

The car failing to crank is somehow related to the starter, the cold weather may be a coincidence. It's hard to tell based on it only failing once. Sometime starters get a "dead spot" and will not work if they happen to land in that spot. Sometimes they work again after several attempts. Also, tapping the started with a stick sometime moves it enough to make it work again. If those are the symptoms, it may need a starter.

check your grounds
electrical wiring has a lot more resistance when very cold and very hot. so a marginal ground will be ok when the weather is temperate and a problem in very cold or hot weather.
check and clean battery connection, ground to chassis and engine to chassis connections. sometimes an auxiliary ground strap from the neg on the battery to a starter bolt will cure a problem like yours when all else fails. if the ground is good then see above post. good luck tom w

cold start
Respectfully to tom w, the resistance of copper wires (all conductors of electricity do this) actually falls the colder it gets. And, you could have a failing starter, but check the grounds (and the battery connections).
I do think tom is right about the grounds and you should probably take off and clean all ground connections and the connections at the starter. They can be looser and fail with lower temps. Also, according to my MB manual, a good battery has 65% of it's current output at 32F versus 70F. |
