Manual light stays on sometimes

[Elvia]

Started Wednesday. I noticed when I started the truck that morning the green light was on in the off position. Everything works, as you can hear the pump running in on and manual. After awhile, I turned it off and light went out. I know that when filter is dirty, the light will come on and off when in automatic. Would this be an indicator of dirty filter also. I have about 3100 miles on this one. Thursday it was on for a little while, But not all the time.

The lighted switch is in the on position when you push it at the top. When the switch is in the center position it is off and when it is at the bottom position it is on manual.

I am not sure what position the switch was in prior to you turning it off.

If I let my vegioil tank get low and turn a corner the system will switch over to diesel because it sucks air. I just keep my tank topped off and have not had that issue since.

When I started the truck that morning the green light was on in the off position.
This was starting cold in the morning. Switch was in the off position from the prior day. So, the switch was in the off (center position) when it showed green. when put in auto position it went out until operating temp was reached. then it turned green as it should. Later when I stop, and shift the switch to off, ( I make many frequent short stops, so, I just turn off instead of repeatedly purging.) the light will stay green. (in the off position).
Now this does not happen all the time, just sometimes.
Tank is at 50%, so, its not low.

This is odd...maybe a wiring issue in the switch?
Not sure, Jason will have some words of wisdom i am sure...if he ever gets on here...

[Elvia]

I don't know, Its worked fine for months now. I have one of the new switches, that glow brighter

Maybe your pressure switch is going out. When my pressure switch failed the light stayed on in all positions. Try using the jumper wire that came with the kit. If you hook up the jumper wire and the light goes off, the pressure switch is probably the culprit. Good luck.

Hey guys we have a pressure switch problem so please give us a call on Monday and talk to Jason. Were not sure what has taken place on the manufacturing of our last batch of switches but we are starting to see a small surge of people with this problem. So please rest assured that we are working hard on getting this issue resolved for everyone ASAP! We have reason to assume that the three wires coming out of the P/S are shorting together, we just don't know why yet.

[Elvia]

Thanks for the heads up. Am I correct to assume that the system is otherwise working correctly in auto, or should we run in manual once operating temps are achieved?

Elvia can not say for sure but when the pressure switch went out on mine I ran in manual because it seemed that on shut down and start up it still smelled like oil not diesel. Manual worked like a charm though since I was 400 miles from home.

Thanks Tanya. I'll try that till the new one comes in.

Green light stays on when in off position

Similar to some of this but my situation is just a hair different...i just changed the oil filter a few thousand miles ago and I always filter my fuel going into the tank...last filter lasted 15K+ miles. Yesterday from a cold start, everything ran perfectly in automatic mode. I was playing around and toggled the switch to the off position and the green light didn't go off. Then I noticed when I put it back on oil the truck surged like it got a boost of power. Does anyone know why the light would stay on in the off mode? I ran it again this morning and all was well and looked normal, but again, when i toggled the switch and at shut down, when i turned it off oil, the green light did not go off. An hour later i restarted the truck and the light was off but i'm sure if I kept going and the truck got up to temperature it would repeat. Is this thing working ok? Anyone?

Maybe it stays on durring the 10 second purge...did you check that?

15K miles?!?!?!?!? Crap...LOL.

On another note, I saw James's comments on the pressure switch issue they were having. Does anyone know how to tell if a person has the faulty switch, or are they not marked?

I'm just curious if I might have one...I seem to be burning through filters much faster than I should.

[MCRVO6.0]

Nope, not yet, I'm still piecing this together...i'm looking into anything i can get a lead on at this point because this is the first quirk i've experienced and the posts from others don't fit. It just doesn't make sense...the diesel side seems to lose a little power (like if it were starving for fuel) when i shut off the oil and the oil side wants to keep working for much longer than minutes with more power but starts normally when cold...It just started yesterday out of the blue and i tested it on the way to work. it also shuts down normally in automatic mode but i have no idea what its doing because the green light is on when normally it is not after i pull the key out...Its not like i'm running a ton of oil either, i just got a batch but i found #2 for $2.99 and figured i'd save my oil for when OPEC cuts production...

hmmm

I guess i don't know what the average life of a filter is, but i had a source of food grade nut oil that probably helped my filter life...plus my transfer pump has a 5-10 micron filter on it...this condition i'm seeing is different than a clogged filter, the light kinda flickers before staying off when it was clogged.

Maybe i'm spoiled with good oil, but the well is all dried up now... so sad.
