Hoskins FT 101 Fuel Flow not working:

1.  Lights stay on - all zeros

2.  Unplugging connector in rear gets it working for a while, then it goes to #1 state again.

3.  Resetting by doing #2 does not carry forward any fuel used between resets.

4.  If reset it every time it goes to state #1, it will accumulate all the fuel used while working.  Only missing that used while in state #1.



Since it always shows some power applied, I do not think this is an intermittent power problem.



Since it accumulates, I do not think this is a problem in the wire going to the battery for residual power to retain accumulated fuel.



The transducer has three wires to it, maybe one of them is the problem.



Since doing #2 always fixes it, maybe the problem is in or near this plug?



Any ideas help??



Wiring diagram is available at

Look in the POH for the FT101A.  It shows the plug pin diagram.  Although I have a 101 the only difference I can tell, is that the type reading - gallons, pounds, etc. - is user resetable vice manufacturer set.



Thanks for your ideas.  Need to fix it tomorrow - Sunday 7/19/09

 Roger,



If doing #2 always fixes it, I suggest that you not use the plug, and maybe see a gastroenterologist. Sorry, I couldn't resist.
