Friend call ask me to stop by & help him with his truck on the way home tonite (85 Ram 150 318 auto). Got there & walked up as he was trying to start it. I heard two pops followed by smoke comming up from the drivers side of the firewall. I said STOP but he didnt. Continued to try to start it as I walked up & it looked like smoke was comming from where the column comes through the firewall. I heard 2 more pops before he say the smoke & stopped. He said some was comming from under the dash. Now we have no fire so it only spins over. He had put brushes in the alternator & was having trouble getting the bolts loose so wanted me to tug on em a bit. I never got the chance. He's not to good & fixing stuff. I have to lend assistance all the time. I think his truck may have blown a fuseable link, but I know very little about electrical stuff. Can anyone offer some good clues or things to try. He needs to get it running soon. ALso he's a bit tight & want spen any money if he can help it.

Sounds like he cooked the wiring harness , look at the back of the ammeter and at the wires going to it and thru the bulkhead .

We looked at tall of the wiring harness. Could still smell the burnt something, but all of the harness looed ok. Even under the dash. Took the bolt from the bulkhead out & all of that looked good. No sign of a problem. Something got hot, but no evidence of what or where.

check those fusable links at the big triangle rubber connector were all 4 wires come to 1 wire to the batt

look them over real good,they can be burnt into but not all the way thru the coating

feel them and see if they feel swollin and soft

look for small splits in the coating

use a test light and see if the + side of coil gets hot with key on

check to see if the BR burnt and broke

may need a new cluster for the dash,PM me I have one he can have if you want it

if the coil gets power and no spark,ecu could be fried or the pick up in the dist

this is were I remove the elect dist and drop a points dist in

remove the - wire from coil and hook up the black wire from the points

then unplug the ecu and see if it gets fire and starts

I have fixed many 85 truck by swapping the dist out to points and never have another problem out of it

I have cut the triangle rubber splice out and wire nut the wires back together also to shortin the fuseable link wires

band aid but works in a pinch

Thats good stuff too. We did not check the amp meter for some reason. We did check the fuse wire at the battery. A red with witha connector. It looked ok. The smoke may have been the amp meter & I wish I had at least looked at that. It was in the firewall area. He said he saw somek under the dash so that is a good idea.

red with a white plastic plug you can undo?

thats not the fuseable link connections I am refering to

at the rubber triangle one of the wires goes over to dist..blue I think

may have burnt the circut print board on the gauge cluster and got the smoke in the dash

85 have all plug in stuff on the cluster/print board and is not like the early amp gauge that has 2 wire bolted to it..those are know fire starters and mopar kinda fixed that by 85

but most 85 ones the guage never moves anyway,at least none of mine have

test ot see if coil gets power is the first thing I would check

I can take a few pics of my 85 truck and the splice work I did to the wire harness

I swaped in a pertronix points conversion and jumper the BR for full 12 volts to conversion and leave the ecu un hooked

did mine 5 yrs ago and never had a problem after that,went thru a couple alt before the swap also

i fixed 2 wires at the fuse link connection

in the pic you can see 2 wires I have as jumpers on them to get home

the big looped red wire on the inner fender

I used some speaker wire and after a few weeks it would burn the ends off and have to retie them

bumped it up to 2 speaker wires and it stoped burning them till I got it spliced correctly

First stop talking about more changes to this vehicle! I would look very close at the brushes you said that he fixed. I had a friend do the same thing and the next thing you know the trucks wireing was smokeing like you explained . The reason was that he lost the inslating washer that keeps the brush ftom contacting the case of the altinator . This is where I would look very close if the insulating washer is missing do not turn the key on or you may burn all fuseable links you ever relace until you fix the uninsulated brush contacting the case of the alt .

It really doesn't matter what type of mechanic a guy is, if it doesn't work after he touched it, look there FIRST. We are all capable of making mistakes.

Lots of good info. This is what I needed. Thanks very much to all I have a lot on my plate tomorrow so I may not be able to get back over to help him for a day or 2. I think he is convinced he needs to leave it alone. Will check the coil. And look at the brushes. Also good to know about the dash circuit board. I am more confident now I can get him going again! Thanks again.

UPDATE: Got over tonite to assist in the repair. Took the cluster out. Everything there looks ok. No sign of anything burnt. Swaped to a different coil that we know works. Still no fire. Rechecked all the wiring we could see & get to. All looks good. Truck has what looks to be a computer mounted in the drivers fender well area behind the battery. Dont see a ballast resistor.

i dont think an 85 will have the computor hanging on the fender

that would be 86-up IIRC

none of my 85 have been that way,I have swap a bunch of 85 wires harness

I just riped and 88 tbi apart with a computor on the fender to get rid of the same crap...not getting fire to the coil

I have seen them hacked into and points added with a BR wired in

and when the alt runs thru it,it also can be bypassed by wireing in a plug in VR and bolt it to the firewall

I just swap the whole wireharnes and call it done

did it today as a matter of fact..85 manual tranz harnees into an 88 cab along with the steercolum for floor shift in my 440 truck

I would get a test light and start checking wires with the key on and look the fuse links over again

or start looking and about 2 hrs of R&R

I think I have him convinced to take it to a shop we both use & are confident in this particular mechanic. I think we could be chasing this for a while if we dont haul the truck to a shop.

Check the ignition switch and its connector real good. Take it apart even. Its the large gray curved one. Be sure nothing is melted or anything. He could have killed the switch. Also check the wires where they come out of the column. Mine had them rub against the ignition lock piece (manual trans) and they shorted out intermittantly.

If all else fails, look at the switch itsself. If its a non-tilt its in the column. If not its down on the column bolted up under the dash.

If its a tilt its down there on the base of the column but if its a standard non-tilt then its inside the column, hence the wire suggestion. In '88 they went to a rod style but his '85 should have the switch in the column if its a non-tilt.

Could not find a switch of the column shaft & the truck is a non-tilt so it must be un in the column. We where going to haul it to a shop today, but he got tied up. Looks like thats where its headed. I appreciate everyones help & input.
