Hello,
I have a older Jet Central Rhino (gas start) that I tried starting the first time to me. I was getting a bad glow plug error, I replaced it with a new Rossi R8, and I watched it glow for about 2 seconds and then the same info came up bad glow plug. I repeated it again, same thing, any idea's?
Thanks, till next time

Are the plugs blown? I’m assuming yes, but if they are not, you have a bad cable or connection, if they are blown, you need to lower your glow voltage on the start parameter menu, try it outside the engine, lower the voltage and go up slowly until you get a solid bright glow, but if the plug blows, you went too far.

also, are you prepping the plugs by pulling the coils out?

Hello, Again.
The plugs are not blown, voltage is at 1.5 volts.I thought that at first I had a bad connection, so I jumped it with a alligator clip and still had the same results.Coils are pulled out

Hello jerrybern
If the plugs ar not blown and the connections and wires are fine, then it has to be the ECU
Most likelly we can fix it, please contact Manny Rodriguez at [email protected]
