1976 W114/115 300D not starting
Okay, so I purchased this car last Sunday for a grand.
Ran beautifully, had a little trouble getting started but with a new battery did fine. Got it home, turned off and it wouldn't come back. Hooked a charger up to it with the engine start mode and it fired up , but then that charger broke. Other night had it hooked with the jumpers to the f250 diesel and it would turn over, quick too, but just wouldn't fire up. Now I purchased another charger, and let it charge, now the car wont even turn over. Battery light stays on until the battery drains itself. I turn the key, glow plug light lights up, goes off after 20 seconds or so and I go to start an click, nothing now. I'll see a spark come off the battery, also after that I'll have to push the battery a little get the connection again. I was thinking internal voltage regulator. Checked fuses, they all look decent, or connected at least. Any suggestions? |
Answer
Sounds like a bad connection at the battery terminal has blown the voltage regulator.
you may find this thread useful and interesting. http://www.peachparts.com/shopforum/diesel-discussion/321775-welcome-fleet-1976-w115-114-300d-dark-green.html . |
you can blow those ? like the brushes ? I tried removing it but the tiny little flat head screws are sucha ***** to get off. especially with not alot of room in their. The wires going to the regulator were frayed a little and exposed metal, could it have grounded out on the alternator ?

Grounding the wrong alternator wire to the case can blow the voltage regulator. Pictures of the wired damage, may help diagnosis. I agree, the screws are a PIA in the tight space, IMO it is slightly easier to remove the alternator and work on a bench. . |
FYI
You really need to read this
I have documented many issues on my daughters 1976 300D in this thread. http://www.peachparts.com/shopforum/diesel-discussion/321775-welcome-fleet-1976-w115-114-300d-dark-green.html . |
Would having a blown voltage regulator prevent it from starting ? Even with a fully charged battery

Odds are there is a glow plug or valve adjustment issue. Seriously plugged fuel filters can also be a factor. . |
The glow plug light comes on, yet I don't here any click or noise from the relay, would the light come on if there was a problem? I'm about to replace all the inline filters and do a valve adjustment also probably switch over to the pencil type plugs, I'll let yah know how it goes
|
But now that it wont even turn over, it just clicks , you could assume its the starter ?
|
Okaay so I'm dumb and just realized the ground cable looked a bit corroded , re did the wire , started right up! Now onto the preventative maintance
