Hello. Used to post regarding my C280 and am back in a Benz. I just picked up a 1986 190D five speed with 180,XXX miles. The car had been converted to a simple veggie system and stopped running 6 mos. ago.

Please help me with a few issues regarding starting and some misc. wires. Below, please find two wires from around the battery box. What are these to?

Now for the no-start. I reverted the car back to stock fuel system and replaced all of the hoses with proper metric hose (from tank through to pre-pump/from pump to filter/from filter to injection pump). I have also flushed the tank and refilled with proper diesel fuel and am getting proper flow to the filter from the pump (per WSM). I have also replaced both filters.

There was a blue green wire hacked in the glow plug harness that I properly reconnected with industrial crimping.

The battery has a full charge and easily starts my V8 and is the same spec battery (Porsche 928).

The fuse strip is intact and I am getting 12.49 volts to both poles, and ample voltage with the key on glow. The glow light goes on for 8 to 10 seconds.

I have to review the Glow Plug section of the WSM, but what would be the next best thing to check?

Any help in wire identification and next steps would be greatly appreciated.
