bombi problems

[JimVT]

I went out for an afternoon run with my bombi. i was going good and all of a sudden my ignition failed. don't you just hate that? 1/2 way up a mountain 7 miles from your truck. Getting dark.
I got a ride out on a snowmobile.
Everything points to an ignition module . I converted it to electronic last year.
The snow trac is going to the rescue to fix or tow it out in the morning. i am going to pick up a module in the morning. I hope a pinto one works. It has that 4cyl industral ford in it.
No spark at the coil wire.
Maybe I'll get a photo of it being towed.

Check for voltage going into the coil. May have a broken wire.

 

[JimVT]

i'll do that. It has the 1980 orginal wires in it and could have a break. It was getting dark and i looked the wires over kind of fast.
I had lots of snow kicking up and the engine was all wet when I opened the hood.

 

[muleman]

If it was real wet it could be drawing down the voltage through cracked insulation on the wires. If you go back and it fires right up I would look for that and a weak or cracked coil.

I had a Bombi that all of a sudden acted like a dead battery and would not start all the time. I sold the bombi to Boggie and he found one of the ignition wires was not the proper size and caused the problem, only in Bombis!! There was a post last winter all about it!! Would be worth checking out when you get it back. Sound similar to your problem.

I has a similar problem on my Massey Ferguson 35. Turned out to be a bad coil.

am aware of the light starter wire on the bombi. I never had a cranking problem. I thing I may have to fix the problem with snow dust entering to engine compartment after returning home. Everything dryed out good when I was troubleshooting it . At least it looked that way. The eletronic pickup in the distributer cab looked all clean and dry. I have no output from the coil wire so I just need to follow in that direction. The Battery is new and strong. I have an extra coil I carry in the snow trac that I am bringing in with me. I hope all 12v coils are the same.
Thanks for all the suggestions

Good luck

Jim all coils are not the same first using a test light check for constant 12 volts on the positive side if good move to the negitive side you should have a flash when canking if the negitve flashes and you have no spark replace the coil if you have a constant light replace the module the coil must be for electronic ignition and if it restarts when cold suspect a coil

Only advice I have is to source a points distributor and take that along.
( generally carry a points distributor and electric fuel pump as a emergency get home kit)
I would think that a (Skid steer,pinto,ranger PU,) distributor should be available an cheap. those ford industrial engines were in alot of equipment.

One wire to make spark, Even without a condensor you can get a long way with just a screw driver and a nail file.

a new coil got me good spark . I am not sure why the old went bad. It didn't have many hours on it. i had it bolted to the engine maybe the vibrations cause it to short??

 

[Snowtrac Nome]

if you did an electronic conversion you may still need a resitor in line to keep the coil from over heating i had the same problem with my jeep so i sourced a coil with an internak resistor and have had no problems since

The kit I put in gave you an option of having one or not. I chose not to have it. you can see it beside the bad coil that it being replaced. I'll put it back on.
