No, sir... Trailers only.

It sounds like a dead short heating up a breaker. Are these trailers ABS equipped? If so make sure the module is working correctly.

Dead short or at least a bad/ corroded connex, possibly in the Ground circuit which seems to present the most probs on the older trailers (that spend a good deal o time along the Gulf Coast.) All circuit breakers associated with the lights affected have been replaced, with one 'boosted' from a 5A to a 10A breaker with no change. No breakers have tripped in relation to the prob..
ABS!? Oh Lordy. Our ABS situation is bad - faulty modules, wiring harnesses, (miscommunications between our specs/ tractors and the Mfrs), plus the Corrosion Factor... plus hard headed shop personnel.. ; )
I do indeed suspect possible ABS involvement. But getting the schematics on any of the ABS circuits is as big a hickey as my above-posted issues with getting IH Manuals...

IH went to multiplexed wiring if I'm not mistaken so I would get them to check that also. Good luck it sounds like a good time to leave it at the shop and tell them "Call me when it's fixed!"

Multiplexed is correct. And one major reason I'm seeking to acquire manuals & schematics on the truck is the apparent lack o same in our own terminal Shop, (ie: they're not showing their cards and they know what I want...). If I
had the dope, I'd be willing to share it for the good o the whole.
As I posted originally, my shop here has indicated to me sufficiently that they have no idea where to start and Don't Want To. :roll: That's warning enough for Me. As for going to a Dealership, once it was discovered that I found a workaround for the time being - there's a profound hesitation to get me 'worked in' for an unknown amount o Downtime.. coupled with my need to "get while the getting's good" out on the pavement.
Rest assured - if the whole thing goes Bloooey or becomes otherwise unsafe, you betcha I will Park It and get medieval. :thumbsup:
Until then, if this gig was easy - they wouldn't need Us.
Many thanks for the response.
For the benefit of others in similar distress, I will keep any news posted..
Surely this can't be that isolated a problem out there! LOL
