Hi Gang!
Tuesday, I put the spare battery from the 240D in my 91 300D and it
fired right up without any charging needed. I put my DMM on it and it
read in excess of 13V and after the GPs heated it fired instantly.
Today, I planned to start it and maybe run it around the block - maybe
more just to give it some exercise but when we turned the key, not even
the lights in the dash are lit! So I got my DMM again and checked the
voltage in the battery and it is down to a little over 2! But I can
charge it. I disconnected the neg cable and it is charging at 40amps.
My question is (finally, right?) and I need to know how to find the
short. Just out of curiosity I checked the Fuses and found fuse "C" was
blown - something unusual - I checked the map and C protects the seat
motors, Trunk Light and some other stuff - I'll write all of that down
shortly.
So, I can disconnect the battery to prevent discharge but I'm wondering
how to troubleshoot what I always called a dead short.
I can pull the fuses one by one and check the rate of discharge but with
so many fuses that'll take a while.
Thx,
LarryT
