Mahindra 1815 blowing 50 amp fuse.

[koshari]

I removed the jumper bar and (I'm not sure what scale I was on) but I got 6 on all 3 glow plugs and I took the glow plug controller apart because I couldn't find a ground in the connections on it and every thing looked new, coil, contacts, and circuit board showed no burned areas so I would think a 50A short would be obvious in the wiring somewhere but I cant get a wiring diagram because the web site prints out a 3 page diagram on one page in micro print, imposable to read.

divide and conquer, disconnect all the glow plugs and try, if it blows its the control cct, if not connect glow plugs one at a time and try. if it points to one particular plug isolate it and try to see if the fuse stays intact,

75 ohms would indicate a dead short that would cause the fuse to blow.
