I wanted to share a successful workaround for a "no-spark" issue on a 2009 LT-A400.
This is specifically for cases where the CDI has been diagnosed as faulty, but the age or condition of the machine makes the cost of a brand-new OEM unit hard to justify.
Note: This modification compromises the factory “no-start” circuits.
On some malfunctioning CDI units the internally damaged circuitry is only partial.
Feeding full time power to the Parking Brake pin, the unit is triggered to bypass the internal fault and produce a healthy consistent output to the Ignition coil.
The Modification
See the second diagram attached below for the wiring specifics.
The Result:
The machine has clocked over 1,000km since this repair and is still running strong with no ignition dropouts.
⚠️ IMPORTANT SAFETY WARNING ⚠️
Please be aware that this modification compromises the factory safety "no-start" circuits.
The machine will now start in gear. The safety interlock involving the handbrake is no longer functional. The machine can move unexpectedly if the starter is pressed while in gear. Proceed at your own risk. If you sell the machine or let others ride it, ensure they are fully aware that these factory safety buffers have been removed.

I pulled out my Big Bear needed to do a few things probably havent been started in a year. Gassed it up charged the battery started right up. I have been using it around the property for this and that. Went to hook up my trailer to pull up to the house while it was idling it quit. Went to start it turned over but wouldnt start. After trying a few more times lost all power. Pulled it up to the house with the John Deere, the first thing i checked was the Universal fit soloenoil from Amazon and it was only a 10 AMP fuse so it does not universally fit the big bear it should be 30 AMP fuse. At the time i remember noticing it but forgot, at the time i had other problems like wiring harness being in a box stuck engine and no spark. when i bought it, yeah i know, thats one ishould have walked away from, but if i go to the trouble of hooking up my trailer and going there, its following me home.
Thats old news, i still need to check it all out see if it lost spark and see if the starter shorted out it was acting kind of sluggish, i replaced the fuse with the spare 10 amp and blew immediately. I will try a 30 and see what happens.

I have a 2009 Honda rancher that has fuel coming out of the injector but will not crank. I can spray gas in through the breather and it will run a few seconds. Any help appreciated

Hello everyone.
I'm working on a 2014 Yamaha 700 Grizzly and having no luck accessing the diagnostic mode on the display. I have tried with the fuel pump connector plugged and unplugged, and select and reset buttons depressed simultaneously for up to 30 seconds with no luck.
I could sure use some assistance if anyone has any tips on this
