OD light.

Hi all , got the 94 idi f350 double cab dually , this truck has the 235/85/16 tyres on front & back , are these the right sizefor this truck , just wondering as i have the OD light flashing all the time , checked voltage @ the IP & all is good (1.5/4v) , disconnect batteries & the light goes off for a days driving then starts flashing again , maybe the tyres are to big?

I assume this has the E40 trans as it's an early 94 truck?

TIA.

it does have the correct tires and it does have the e4od.you od light flashing can be caused by the tach sensor on the side of the ip gear housing.right behind the vaccum pump there is a 1" nut with 2 wires coming out of it .look and see if those wires are getting bare
