Installed a fully charged battery, big spark when connecting the negative cable. Big draw immediately starts pulling down the battery. Unplugged the glow plug harness so no power can get from relay to plugs. Big drain still there.
Left the glow plug harness off, rigged an amp meter, looks like roughly a five amp draw. Now I've got the battery charger on this battery, while I pull fuses and check for the draw to go away. I think the alarm system pulls a big load while it starts up, but that's probably normal. I need to rig up that trouble-shooting light someone described to see if I can speed up the diagnosing step. -- Max Dillon Charleston SC '87 300TD '95 E300 On October 27, 2018 2:34:46 PM EDT, G Mann via Mercedes <mercedes@okiebenz.com> wrote: >Yes, I believe the result of higher current indicates a shorted cell in >the >battery...
