    ford 555d alternator not charging

    I have put another alternator on and it is still not charging. I have voltage on the indicator terminal and the B+ terminal. There is another wire that is on here besides the W terminal that I am not sure what it is. I also think that this has the regulator on the alternator. I will post a...

    daewoo 255 lcv solar excavator throttle issue

    Yes, there is an epos module. I have very little information about this machine. I had a generic schematic that the customer had but doing continuity checks i am finding out that it isnt correct. Trying to find the correct complete wiring schematic.

    345BL - How long should the stick stay in the air?

    As far as the stick in the air, it all depends on the shape of the circuit. When the parts get some wear on them they will not hold as long and drift down. There are drift specs and are usually just a couple of minutes, somewhere around that. I have never heard about purging air by putting...

    daewoo 255 lcv solar excavator throttle issue

    I have got a daewoo 255 excavator that has no throttle control. It will start and idle but nothing else. I have a code 24 active which looks like it is for the tps sensor voltage low. I have repaired the wire harness where mice chewed in the pump house, but it is past the throttle motor...

    740b regen headache

    I did do an ohm test on the swirl plate to ard housing and it was .4 ohms. I ran jumper wires from the swirl plate and the ard housing back to the coil bolts and there wasnt any change in the spark.

    740b regen headache

    Well I finally got this beast figured out. I put a new coil and wire on it and still had the spark jumping around and weak. I then put another spark plug in which makes it the third new one to go in and i got a better spark and it wasn't jumping around. Tried to do a regen and it still failed...

    740b regen headache

    Yep, i slept on it and i remembered it does ground at the mounting bolt for the coil. I have tried a coil wire off of another machine that was working correctly and no change there so i guess i have eliminated one link in the chain. Unfortunately we got 7 inches of snow last night so i wont be...

    740b regen headache

    I was wondering if the spark jumping down around the porcelain was not normal. One other thing I was thinking is that I had the ard head just laying there and it was sitting on some hoses. Would the white wire ground the ard head? I am not sure where that white wire goes to at the moment. When...

    740b regen headache

    Pulled off the ard head and went to override the ignition transformer and watched the spark. It is jumping across the gap but i am not sure if it is strong enough. I am also seeing some spark from up in the porcelain to the housing. I will upload the video when i can get my computer to accept it

    740b regen headache

    I got to the machine and installed a cleaned dpf filter that customer had extra as their one out of this machine was cracked. Got the filter in and reset the ash interval and reset the codes. Could not reset the first level high soot level code. Before I could even get the engine warmed up...
