Aqua-Hot Stopped Running Under Diesel

December 28, 2012, 11:01:12 am

Good Morning!

I have a gel issue and added anti-gel to the fuel and had no gel issue with the engine after that.

However, yesterday I thought I heard the AH hesitate momentarily while running on diesel. I went outside several times to verify what I thought I was hearing but never caught it hesitating once.

I went to turn the AH off last night and saw it was already off. (It gets down to the 40s here in El Centro but no hard freezes -yet)

But this morning when I went to turn it on I saw the diesel switch was already on - but not lit.  So this means the AH stopped while running under diesel. And will not relight.

I was looking forward to getting an annual service in Quartzsite at the Lemon Rally.

Any suggestions in the meantime would be appreciated.  Is it OK to run the AH electric?

best, paul

Morning Paul,

It is fine to run on electric.

How much diesel in the tank?  The fuel pick up for the AH only goes down to about 1/4 tank level.

I checked the tank a week ago and it was fine.  My VMS 240 CL tells me the engine has burned only 63 gal from a full tank.

But I'll check again now.

Later,

best, paul

Right.  The tank is more than half full. The VMS 240 CL is not lying ... yet ... ;o)

Paul, Sometimes when the diesel burner has been resting for a while( summer season) the igniter has a little trouble lighting the burner. Give it a few tries, ie., turn the switch on and if it doesn't light repeat a few times. If it lights and goes out soon (a more likely scenario) keep repeating several times watching the results, it will after a few "does" stay on, probably. A lot of very white smoke is likely for the first few burns and is normal.
Yes it is OK to "burn" the electric element.

Paul,

If Horace's suggestion does not get you going, hang in there on electric till you get to Quartzite.

Roger Berke is there now and Art will be shortly.  One of them can get you going in style again.

Oh, good!  I had corresponded with Roger earlier for an annual in Q and I somehow got the impression he was not going to Q.

Yet, again, I remembered something before it happened ;o)

Sheeesh! Is there no end to the treachery of growing old ...

Here's hoping that the problem is some gelled fuel remaining in the aquahot and running it on electric will clear it up.  Sometimes ya get lucky....
