Hello,
I was just reading a recent thread where DR H was used to test ignition coils (and fuel injectors). Was wondering how that was done ?
I have a 2017 BF250. Last summer at 580 hrs, I was only getting 4800 RPMs at WOT and it was sounding like there was a miss. I was expecting to get 5400+ RPMs.
I used the "igniter test" on DR H (BRP version) on all coils. I pulled each plug, inserted the plug back into the coil, and grounded the plug against the engine. When I pressed the test button on DR H button, I could hear a snap at the plug but saw No spark. It was the same for each cylinder. I could Not tell the difference between any of the coils. DR H reported No error codes as well. Maybe these old eyes just don't work well on a sunny day ?
The #3 plug had pretty good burn marks on the ceramic. I replaced all the plugs and the #3 coil. Throwing parts at it worked this time. I was back to 5900 RPMs and none of the plugs showed any issues 6 months later.
Was also curious if anyone adds fuel injector cleaner directly to the offboard, water separator/fuel filter as a preventive ? I have never used fuel injector cleaner and the engine has 650 hours.
Thank you.
