Screwed up. - Upon connecting the battery and tightening the Neg terminal, the 10mm wrench slipped, bridging the battery Neg post to starter relay. I swear I seen a blue ball of fire when this happened.

Fired her up and had a MIL right away. I haven't seen that light on in quite awhile. Plugged the scanner in while she was running and pulled a PO113.

P0113 Intake Air Temperature (IAT) Sensor 1 Circuit High

Strange ehh. Well, tested it out, VREF @ 4.60v from the PCM, -that's okay I guess, would have liked to seen 5 volts. Resistance should change on the sensor itself from cold to warm. No change. I have two new IATs on the shelf, so I tested those the same way. No resistance warm or cold with any of them so I guess I'm testing incorrectly or my Fluke meter is junk, - doubt that.

Anyway, I disconnected the battery again for an hour or so, - restarted and everything's fine now. Seems to be, I haven't driven the truck yet, no CEL and it runs great in the garage lol. I just hope I didn't damage the PCM.

 

You will need to complete 2 drive cycles to see if it is going to come back. Right now you would still have a DTC P1000 ( tests not completed ).

When you bridged the neg to the start motor relay, did you take out the mega fuses ?



These are in the middle of the starter motor relay to the battery.

 

Nope, didn't blow any fuses. Think I got lucky , it's running fine. Yea the MEGA's are first in line, but their fine.

 

dont think the truck would crank if the mega was blown

sounds like you're gonna be fine. might have just kept this one to myself tho :o

 

I don't care, could happen to anyone. You have to position that wrench perfectly for that to happen. One side of the relay has a rubber boot like deal on it, protecting it. The other side never had one. I do need new holders for the 175's tho. Their exposed, factory covers fell off long ago. I was just looking at some from Bussmann -

 

BTW- P1000 isn't part of my program, never was. I can see what monitors are complete and which are not, but I don't ever get the DTC P1000 in this 98.

 

I was just asking if they blew and you replaced them.
Without them, that would be no crank truck.

Don't know how it made that big of a flash and did not take out the fuses, should have.
Obviously it not reach the inrush value on 175 AMPs, when it created that flash.

Strange, did not know the 98 did not have P1000, wonder what year that started, I would have guessed 1997.

 

well flash with the wrench shorting is isolated at the battery, while you can screw up things on the car, its more then likely to burn your hand, melt your ring on your finger, or blow up the battery then taking out a bunch of stuff on the car

 

The Flash was @ the relay. Keep in mind, BOTH 175 Mega's connect to the relay post. The fuses took the hit together. There's an arch mark on the relay nut. I just noticed that the protective cover on the relay nut was switched to the smaller red wire side of the relay. The nuts on the relay were switched as well. One nut is a 15mm, the other is a 14mm. The protective cover fits the larger relay nut. I figured this out looking at my old gallery pics lol.

So the only thing strange that came of this, - is the PO113 at first.

 

Yea, no burns or shock. For awhile, I was seeing a light show when closing my eyes. Entertaining for awhile, but short lived as it eventually went away. Fired it up again and ran it thru the gears, all is well.

 

I took a few pics so it's easier to see what I need to do yet. I just upgraded my system for e-fans, inverter and amp. E-fans in the future, wanted to 3G and upgrade cables first. Like I said tho, I have more to do, -ran out of adhesive heat shrink for the cables and need to get new holders.

Another pic -

 

Crap, I just noticed I laid the wrong wrench out in the pic, - 10mm not 7/16. :o

 

I'm really surprised it didn't take out that mini 20amp fuse. That's tied directly as well. It's fine tho.

 

The mini is connected via Yellow wire. Loops to the 175. NOTE: Wire color changes @ holder. From Orange to Yellow.
