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.

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 ![](/ubbthreads/images/graemlins/thumbs.gif) 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 ![](/ubbthreads/images/graemlins/popcrn.gif)

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 ![](/ubbthreads/images/graemlins/laugh2.gif) test ot see if coil gets power is the first thing I would check ![](/ubbthreads/images/graemlins/thumbs.gif) 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

forgot the worked on alt part, and you said he was not to good at that sort of stuff and you help him a lot
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.

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 ![](/ubbthreads/images/graemlins/boogie.gif) I would get a test light and start checking wires with the key on and look the fuse links over again or start looking ![](/ubbthreads/images/graemlins/scope.gif) and about 2 hrs of R&R ![](/ubbthreads/images/graemlins/panic.gif)

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.

Look at the ignition on the steering column.Its at the base near firewall.My 84s was cooked.Had to put a new one in and rewire it.They used basically a GM type column on those.Rocky

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.
