Hi all here are some more videos. One is of the clear return line and the other two are Tech 2 data and battery voltage on start up and when the event happens. Hope you can make it out. Still working on getting the WTS light to work. I wish I could narrow down the event of being a...

Hi guys, I’ve been out in the garage checking the truck out and taking videos. I believe I went through all the grounds, all good. Ran the truck and wiggle tested all the harnesses on the truck, no hiccups. Took some videos of the clear return line at the IP. Also in the cab with the Tech2...

Good to know thanks a lot

Thanks Will, you might be on to something. I turned the parking lights on in my dark garage before the first start up of the day and the event happened along with the dash lights blinking. I have touched a lot of ground connections during the engine and trans. swap. And dash removal. I have...

The IP is the second one from Quadstar. The fist one was defective. The second one was rebuilt and bench tested. I do still have the working original one. Maybe I’ll put that one back on for a test. But I believe it was also doing the same thing. I remember seeing the wait to start lamp blink...

Thanks dena, my truck is a 95’ OBD 1 I’m using a Tech 2 on it. Will it work on a OBD 1 ? Maybe that could be the problem of my scanner disconnecting.

Thanks guys, the scanner came w/ 2 power feeds the lighter and battery cables. I’ve tried both. The batteries are recently new and the truck cranks over pretty fast but I’ll check loads. I’ll try hooking the scanner power feeds to a remote battery not hooked to the truck. Someone said it could...

Hi all, I’m trying to use my scanner to diagnose an engine cutting out after start up. Just a fast little hiccup . I want to see what’s the IP is doing when it happens right after startup. After inputting truck data and starting it up, the scanner disconnects and I have to re-enter data again...

I was afraid of that sorry. If you look really close (zoom in really fast) you can see a very small bubble right when it starts. The hiccup is very fast after that. I’ll try for another video. Thanks a lot.

Rebuilt 5521. Second one the first one was bad.

Thanks Pav. I haven’t got to it yet. When I do what do I have to look at on the timing and offset numbers? If they change? The problem I have is I enter the truck data with the key on engine off then start it and the scanner disconnects and I have to re-enter the data after it is running. It...

Yes they did Thanks.

Thanks guys, I ran through the wiring shaking them while engine running and checked codes. No dice. Watch the tach two little blips. I’m convinced it’s happing only on first start up cold. Like I said on the old engine it coincided with the wait to start light blinking. The...

Thanks jrsavole: you read my mind. I was just getting ready to come back on and ask that question. I would really like all four bulbs to light up.

Thanks guys. Yea I am concerned about reliability. I forgot to mention it also hiccups once or twice after start up too before moving the truck. I do remember on the old motor the hiccups coincided with the wait to start light blinking.Seems to only act up before it warms up. I’ll get under her...

Hi all, I just got done w/ a new Optimizer build on my 95’ Duelly. It just started to cut out when backing up. Just a hiccup always in reverse. Never in drive. One time it did shut off. New 5521 IP, LP, known working PMD behind bumper, everything new. Any ideas? Thanks.

Yea, d I’m not going to run DRL,s. I’m not sure i have them. That module doesn’t look anything like the one i thought was a my module. It’s a plastic case w/a circuit board the size of a flip phone right behind the headlamp switch. Does all four bulbs come on when you have your hi beams on...

I guess I’ll have to go to the junk yard to find the DRL module. I can’t find one anywhere unless someone out there has one. Thanks

Do you run spacers in the rear?
