Emerengcy my altanatior died in my 90 f350 7.3 diesel can i run with out one.

i have to be at a trade show tommarow at 9 am and can not get an alternator untill tommarow after noon. once the truck is started will it run. the battries are charged. i will be doing about 50 miles on the highway with a explorer following me for a jump if need. will a diesel run with out an alternator or battries.

It should make it, I'm assuming it's not a power stroke so little juice will be needed.

I drove 40 miles to work in my Powerstroke 7.3 with no alternator, 7 year old batteries, and -20F with my headlights lights on, and I made it just fine.

You will need power to keep the fuel shutoff valve from closing. Just don't run anything (radio, heaters etc)

Luckily the IDI 7.3 requires alot less juice then the 7.3 power stroke. As long as you don't run anything, you'll make it just fine

Did you make it alright Shawn?

yes i made it fine and for the past month i have been chasing electrical problems. found out it was not the alternator. but the positive wire from the alternator to the starter solionid. so ididot at uhaul used a crimpconnector for a 16 gague wire. well i dident find this out untill yesterday when the truck caught fire. minor electrical fire no damaged just melted insulation. i have the parts i need to replace on order and will have the truck back up and running for this weekend when it will be pressed in to service hauiling more crap to a trade show. i hope for the best.
