HI All
I have a G26 converted by ralph. The engine has been setting around for about a year.
I mounted it on a test stand and it would not start, so I tried to trouble shoot it. Charged the battery, changed the spark plug. Upon testing the plug to see if it would spark, I was zapped by the plug wire, so there is/was ignition. I hooked a 12 volt voltage tester and it did not light up (maybe too little voltage between the plug wire and ground)'
Does anyone have any suggestions of more troubleshooting/suggestions?
I even tried to start it with a starter to with no change, could I disable the electronic ignition or just send it back to Ralph?
Thanks in advance
Bill

Maybe if you gave a bit more information about the engine it would help. Is the engine new, or how old is it, or have you ever run it since you've had it. As I was reminded recently, an engine needs three things to run, fuel, air and a spark and if all are present the engine should start.
It is quite possible that your testing fried the ignition, so your best option might be to send it back to Ralph and have him repair it. He can be very tolerant and just might do so under his warranty ..... maybe.

try to do the follwoing:
1. take the plug out
2. IGI to ON
3. hold the plug to the engine body
4. rotate the prop and see if theres a spark.
yes:
put back the plug and injest fuel manualy to the engine/carb and rotate - should start for a few seconds and die.
this mean that the elec system is OK ND YOUHAVE A FUEL/CARB PROBLEM
NO:
check the fuel line' look fo bubbles
check the tank, should be vented so the carb can suck the fuel up!!
check the crab neddle H & L - start with the original G26 setup by the manual and go from there....
elec troubleshooting:
batt charged - 4.8 with at least 1800Mha
see if the sensor - pickup- is conected correctly and the wire harness is OK all the way to IGI unit
see if the small magnet on the new hub for the sensor is still there...!! if not, than the sensor wont get the "feedback" it needs to generate the spark!!!
hope that i helpt in any way
thees are the basics checks that you need to do before you ship it for repair.
good luck
