Oil distributor trucks .....UGH!!

I hate these dam things. You cant get within 10' of one without the mess getting all over you, but life goes on! A Mauldin MPS3500, 3 spray bar nozzles wont fire on the main curbside bar. This is the solenoid box for the right left side spray bar.... which is working as it should.... I open up the problem side Curbside) to find...... HOLY S&*^!!!!! YIKES!!!!! The entire box is full of tack oil and is like molasses in Siberia. I have troubleshot the electrical back to ...... Well, my electrical schematic doesn't have the pin out details for these. Mauldin got that to me late yesterday.. ...stay tuned!!!

Nothing like a little Bunker Road Oil for a BAD Day!!

Figure out which one is cooked

That center DVC41 at pin 11 isnt giving me a drive signal. It is flashing an open circuit/grounded circuit blink code with the wiring unhooked. Looks like a circuit inside it has possibly failed. I asked a Mauldin tech support guy for the pin out detail for these DVC's and he told me that was in the software LOL..YEAH NO ****!!! How in the hell do you wire a machine without knowing where the input and output signals are going??? I swear some of these guys are dumbbb.

At least Numb Skulled.

So this is what I am currently looking for. Of course it was obsoleted in 2017 so I haven't had any luck so far...... I have a failed output at #11. I have been told that these are NOT repairable by Mauldin. What I do know is that the older CAT MD5075 track drills used a system like this and I believe the DVC41 was part of that. I am awaiting a electrical schematic on this track drill to see if I am right. If any of you CAT guys know about these in past machines then I am ALL ears. Im trying to locate 1 to purchase and have the software added to correct this machine problem.

Be glad your not working on a Blue Tree GPS monitoring system, What you have above is way more info than I have for Blue Tree. I'm on the phone sometimes up to two hours talking to some IT guy in India to trouble shoot.

I may know somebody who knows somebody who owns or works at that company. Drive right by it to work every day. Maybe I could rattle some cages for you? edit: it looks like they sold out about two years ago. I'll ask my friend who should know. Moved out of California it seems, what a surprise.

Click to expand... Yeah that's what I am finding also. Turns out that Cat drill used the 10, 20, and the 50.............no 41's. Looks like I have finally found something that Ebay or Amazon don't have. I'm still looking of course, but its not looking good.

Time to Update machine?

Gonna be HIGH!!
