Engine control fuse blowing?

[DLUTES]

Hi. New to site. Sorry post is so long. I have an '02 F250 with a Banks Powerpack system in it. I had an incident where when I was hauling my fully loaded 33 foot toy hauler down the highway at about 65mph + last year, the engine made a popping sound, then motor shut off, clicking sound, and all dummy lights on dash came on. I did not have my CPS replaced yet at the time so I thought that was it for sure. Turns out after investigating, it was one of the Engine Control fuses located in the under dash fuse panel. I replaced the fuse and haven't had any problems since, but I don't think I've used the tow hauler since then. Just recently took another trip with truck and toy hauler and blew 5 of those fuses on the way, and 5 on the way back (about a 250 mile trip one-way). Each time it happens, it seems it's only when I'm under load (hauling), and perhaps when I hit a bump? Each time requiring to pull over, shut down, replace fuse, and everythings back to normal. Has this happened to anyone else out there? Is it a short? and if so where might it be? Thank you in advance.

Welcome to OB!
What fuse # was it? or was it 5 different ones?

Thanks H2odrx, I looked it up and it's fuse # 22. The fuse box contains two engine control fuses. One in # 22 and one in # 23. Both are 20 amp mini fuses. Its always # 22 that blows.

I was thinking the fuel heater was on the same circuit and they have been known to short out

22 is the heater on the OBS i'm not sure on the SD?

That was where I was going too....

It might pay to unhook the fuel heater and see what happens?

#30 fuse --located in under dash fuse panel....also powers the IDM..





Only blowing control fuse when hooked ...does your toy hauler use the 7 pin trailer plug?

Does it have the 12v constant hot for charging the break away battery?

I would first check/disable the trailer wiring and start there.....
