I have read a few posts lately regarding kero plugs not firing up.

Apparently some have had events where the plug gets hot enough to smolder the fuel but not ignite it. This has happened to me and I was advised to check the length of my wiring from the ecu batt back to the engine. I have an excessive amount.

I am trying to figure out whether this is a battery thing or a bad plug, My turbine always starts right up no problemo on a topped off battery (4200 7.2 NIMh). Im sure the wire length is not helping but since it starts consistently when topped off (<9v) I think I can rule out the leads..

Is there an effective way of testing your plug to detrmine its condition? Physically it looks fine with no cracks or other defects that previous posts have mentioned. Also I dont know which version plug I have. What is the lifspan of these things anyway?

Thanks, Pete
