Re: Two Scares In One Day Reply #25 – October 08, 2012, 12:06:44 pm Yes, it turned over well. But never fully started. Just suddenly quit even though I saw oil pressure rising. And VMS says "No faults"best, paul Quote Selected
Re: Two Scares In One Day Reply #26 – October 08, 2012, 12:13:13 pm I've suspected from the start that this was an electrical problem since running with generator on and boost switch on the engine failures and transmission failures went away.If the boost solenoid failed would that mean the boost switch would not light?best, paul Quote Selected
Re: Two Scares In One Day Reply #27 – October 08, 2012, 12:21:27 pm Where is the boost solenoid? I don't see any wall panel in the house battery compartment.best, paul Quote Selected
Re: Two Scares In One Day Reply #28 – October 08, 2012, 12:26:52 pm Hi Paul, On my 1997 the boost solenoid is near the isolator, next to the driver side rear wheel. Not the best area. On later models they moved it to the electrical area at the foot of the bed. Open the bed cover and it may be right in the front area. It is under a quarter inch piece of plywood that acts as a cover for the electrics. I hope this helps.Raymond Quote Selected
Re: Two Scares In One Day Reply #29 – October 08, 2012, 12:38:01 pm Thanks! My boost solenoid is right above my isolator. It not as big as my new 200 amp continuous one ;o)Now at least I can have road service do something I wanted done anyway.best, paul Quote Selected
Re: Two Scares In One Day Reply #30 – October 08, 2012, 01:00:42 pm Paul,Have you eliminated the possibility of plugged fuel filter(s)? The fact that it almost starts, then stops, might indicate a fuel supply issue. Quote Selected
Re: Two Scares In One Day Reply #31 – October 08, 2012, 01:15:00 pm Paul,Just FYI the bulb in the boost switch is notorious for burning out. I'd meter it first before assuming the switch itself isn't working.Michelle Quote Selected
Re: Two Scares In One Day Reply #32 – October 08, 2012, 01:16:04 pm No, I've not eliminated the possibility of plugged fuel fiters. But there was no problem starting at time or two when I arrived here Sep 4.And at that time I needed the generator and boost to keep the engine and transmission from acting up. And at that time the engine would "cough" right after starting, without generator/boost, which is similar to what happened today. I suspected fuel problem then but it never "coughed" when generator/boost was on.Would a fuel problem show up as a fault? My VMS claims "No faults."best, paul Quote Selected
Re: Two Scares In One Day Reply #33 – October 08, 2012, 01:30:45 pm Is the boost bulb burned out?I detect no change in the volts at the boost solenoid when I have the boost switch on or off.But being a Civil, not Electrical, Engineer, I'd guess the boost switch or boost solenoid is bad. But the boost switch did work this morning (at least in the sense it lit up).I'd also guess that with a good bulb and good switch the light will light only if the boost solenoid is working.best, paul Quote Selected
Re: Two Scares In One Day Reply #34 – October 08, 2012, 08:01:20 pm The boost switch bulb has a fairly short life, at least in my case. I think I have replaced it every 8 or 9 months. I've not had a problem with the solenoid itself.Mike2003 u295 Quote Selected
Re: Two Scares In One Day Reply #35 – October 08, 2012, 09:24:11 pm when my boost solenoid stoped working, the light on the switch stayed on. Quote Selected
Re: Two Scares In One Day Reply #36 – October 08, 2012, 09:33:52 pm Dang, gotta stop reading about all these failures on the forum. Had no problems with my boost switch.....till this morning that is. Turned on the boost, the light did not go on and I did not get any boost from the house batteries when starting the engine either. Something else to put on my "to do" list. Life is good.Roland Quote Selected
Re: Two Scares In One Day Reply #37 – October 14, 2012, 01:07:29 am My problem turned out to be a bad alternator PLUS gelled fuel. Alternator replaced. Water separator replaced. Fuel filters replaced.No problem on highway. But engine stopped once while at idle. And hesitated once or twice. There must be some gelled fuel still in the system.Is the solution to just continue to burn thru the bad fuel? Or prayer and fasting? ;o)Previous fuel filter change in May 2012 9,000 miles ago.best, paul Quote Selected
Re: Two Scares In One Day Reply #38 – October 14, 2012, 06:03:25 pm Paul,Diesel gels when it's not formulated for the temperature. Problems usually occur when you refuel in the south and travel north or up. Add an anti-gel additive and top off with fuel at your current location. Quote Selected
