Low Battery, Maybe.

[Bob Mathews]

1984 300SD
Went to start car in the morning, and it acted like I had a low batt. Jumped the car and still as if the battery was low and would not let the car start. took out the battery and had a loud test done. Was told that the batt. was good. bought and changed out starter thinking it might be bad. Changed it out in a very bad rain storm that day. got done and the car now when you turn the key to heat the glow plugs. I get no dash lights to tell that the glow plugs are heating or that power is on, the only light that comes on is the parking brake light ind. and the starter will not turn over. Weather has bin not so good and work so I have not looked at anything else. Any help on what might be wrong and what I might look for and check would be great. Thanks All Bob
