Status: offline 		I purchased a simjet 2300 that is installed on a roo.. He said that it's never been flown and I believe him as there are no control rods and the install wasn't completely done. He said that the turbine had only been bench ran and it does look clean, no reason to doubt that. Anyway, I finished up the install and went to test run the turbine, it cycled a couple of times with only the electric motor spooling up. I checked everything real quick, tried again and it spooled and started on the propane but that's all the further it would go. I shut it down, checked everything out, went to turn everything back on and now the switch lights (cockpit panel display) don't work at all... Nothing, dead. Checked all of the plugs, pulled the ecu and hooked up everything outside of the roo, nothing, no activity....

Any ideas?? Where do i have to send this thing to get it checked out? It was purchased at great northern models.

The fadec is 2002-d2. This thing sure is big compared to my jetcat...

Ps, it has the lipo battery

My 2300 runs great, never had a problem other than this one.

A couple of things to check.
1 the wiring on the back of the switch
2 what size of lipo
3 does the pump turn? Try putting 2.2v from two aa batteries to the terminals to see it turns
4 if you look inside, do you see a white block or a small circuit board attached to the main board?
5 check the starter to see it the wires. Inside have contacted the housing

I replied:

1. Everything looks ok, wiggled the wires, nothing loose, applied power and
wiggled wires, no sign of life

2. 3 cell, 11.1 2100

3. pump does run

4. circuit board, didn't see anything white

5. Everything looks alright there, applied power with the starter out of
the houseing... still dead..

Status: offline 		I've ran jetcat and artes turbines.. I've heard great things about simjet. I'm looking forward to getting this one going!!! We have a jet event here in a couple of weeks.. doesn't look like I'm going to quite make it with this one, lol

Status: offline 		Sounds like the Lipo Battery may be bad or the Control Panel switch is defective.

DO not attempt to perform a start on less than 10.3 volts.

It is also possible that you have a bad turbine to ECU cable.

Please give me a call in the shop this evening and I can walk you thru some additional checks.

Status: offline 		Sounds good. I've tried wiggling and jiggling, hooking and unhooking, applying voltage etc etc etc, lol. I didn't receive any lipo instructions with the manual. On the attempted starts though, I don't believe that the voltage was ever close to that..

Status: offline 		It was definately the ecu!!! Installed the 'loaner' took it outside, put some fuel in it.... Everything came on. It fired on the propane but still didn't kick over to the kero.. I tried again and watching the line for when it was time to switch to the kero I bumped my fuel pump a couple of times to get the line primed.. Fired right up!!! Only thing i have questions about now is the cool down.. This thing takes forever!!!! I bet it cycled 150 times!!! It will slowly drop the temp to under 70 before it stops calling for cool down. The last time i ran it i used my air compressor to help cool down and it still took quite awhile!!!!

Status: offline 		Hi,
A friend has problems with a similar engine. This was an air start engine converted to auto start system. The ECU is the FADEC 2002-D2-R, however, since he bought it from another person he was not provided with a manual.
What presently is happening was that the engine starts on gas but after a few seconds quits and takes its time to cool down. The heat sensor was changed and some improvements have been noticed but still the engine won't start. Last time I heard was that the pump moved a bit but didnt go. Maybe there is the same problem as described above or else its an ECU problem.
I would appreciate it if anybody is able to provide me with a copy of the manual pertaining to the above ECU (FADEC 2002-D2) since there might some clues there too.

I can provide you with my email address should you have a soft copy of the manual available

Any help will be appreciated.

With thanks

Reuben
Malta

Hope you are well.

Did you Calibarte the T/C to the RPM board after change out ? This is done with the use of the IRDT Data Terminal.

I suggest you disconnect the pump form the ECU and run fuel thru it for 10 > 15 seconds using an 4.8 volt Rx battery. DO NOT RUN PUMP WITHOUT FUEL FLOW THUR IT OR IT WIL BE RUINED.

Check to be sure that you have at the VERY MINIMUM 10.3 volts (the more the better) on the ECU battery BEFORE a start attempt. If you do not, the pump will not get enough voltage to funtion correctly after the solenoids, starter motor and glow driver are engaged.

Last but not least, check all filters to be sure they are clean and be sure your fuel delivery system (tanks and UAT etc.) are free flowing.

Earlier this week I had an exact same condition as you have discribed here and it truned out to be a fouled UAT. It had tons of algie in it. Replaced the UAT tank and the engine started and ran every time.

Brg.
