Default Need some help...

Hello Guys,

I'm having major trouble with a glow plug issue...anyone have suggestions as to what the problem is? I'm supposed to fly tomorrow and this is ruining everything.

Thanks.

Chris

Really sounds like the mosfett (spelling) in the ECU is going crazy. This will instantly fry plugs faster than you can replace them. Another thing to check is to be sure you have a good ground and battery connection at the plug.

If all else fails, and you need to keep your appointment : A friend of mine used to start his turbine using one of those click on flame for the BBQ. This was done by igniting the gas thru the exhaust. You just need to keep a close circuit in the glow plug so the ECU continue the start process.
Good luck

How about this, put a new plug, do not reconnect the wire to the plug instead use your glow plug ingniter to glow the plug in the turbine and like Edgar explanied keep a closed circuit on the glow plug wire so the ECU continue the starting secuence.

I was haveing a similar problem with my P60. I got 5-10 starts on some plugs and not even one start on others...plug burned out as soon as I tried to start it. Problem for me was the glow plug votage too high. It was 2.7V (don't know how it got there...I never messed with it). I changed it to 2.1V and have not had a problem...that was about 8 flights ago.

every plug is different
try this :
get a new plug new make sure you pull the coil out enough
now let the plug hanging on the cable and ground it.
set the voltage to 2.1 and look at the colour as you do a start , if its yellow-bright you are ok.
if its red it is to low , to high and you guessed it use a new plug.
this is the way if i use a different plug as jetcat supplies them.

Some years ago I had this problem; it turned out to be a small ball of solder in the wire side of the multiplex plug, when the plug moved it caused starter voltage to be fed to the glow plug, blowing it. Took me ages to find the problem.
