electrical problems

i went to start the 1009 this morning and it failed to start so i checked all the glow plugs and there where a few bad ones so i replaced them all.. went to start it again and all the lights in the dash went out and it wont crank at all.. i have no idea where i should start looking for this problem ( all ready looked at the fuse bo and all fuses looked good) any ideas. thank you

you are saying the starter was turning over but not starting, you replaced glow plugs and now starter does not turn.

have you done doghead mod? if not i would do that next.
glow plugs and starter are not really connected in any way so your starter not working may be because of a bad relay and it is just coincidence that this happend at same time.

if you disconnect batts for glow plug change, double check connections.

Remove clean all battery connections, shiney clean with a wire brush or emery cloth.Make sure batteries are fully charged and load test them.

Make sure your battery grounds are tight first and go from there. These vehicles have to have a good ground.

Start Simple. First confirm your batteries. Have them load tested, and fully charged.

Then consult the TMs if pressed for time. They can be faster than the forum. I have a link to the TMs in my signature. Use key stroke Control and F to search them for key words. There are very good procedures for troubleshooting and reparing this condition within.
