I have a 150 that has no fire to the plug. Any help? I spoke with Jeff at patriot, he believes that it may be the CDI box or coil. I just wanted to know if there has been other problems? also fixes. I pulled both of these off another 150 in an attempt to find the problem, so we will see. PLEASE HELP IF YOU CAN.

We don't have a Y-150 but the below info from our Pred-90 might be the same on your unit...

See our unplugged '03 Pred-90 stator wires at: - Press Here -

For those of you who want to know, the two single wires on the outside is our '03 Pred-90's stator's Ignition Side output wires. The 3 wires going into the white connector are the stator's charging system wires.

--------------------

If your Stator output wires are the same as our Pred-90, the white plug with 3 wires is the power generation stator coil. It's used to recharge the battery and drive DRLs (if you have them). The 2 single wires are the ignition side - used for spark across the spark plug.

Using a digital ohms meter (see below picture), you must get an above 0 reading when testing from Wh/R across to Bl/R. You must get an above 0 reading from Wh/R to frame ground. You must also get an above reading when testing Bl/R to frame ground. If any of these number are 0 (or near zero), then your ignition side of your stator is probably shot - assuming your T-150 has the same ohms readings as our Pred-90 stator system.

For the digital ohms meter tool I used on our Pred-90, surf: - Press Here -


Notes:

1 - Before testing, ensure you obtain the base reading of your Digital Ohms Meter's Probes. To do this, simply contact your Red Probe and Black Probe together until the numbers settle down. This gives you the Ohms resistance within your Probe wires. I think mine unit was .03. Also subtract this number from any numbers you get from the above readings. Hence, your frame to black wire may show .03 on your display but could really mean "0" - if your probe wires had a .03 resistance to begin within.

2 - On our 3 wire white plug, the right black wire is the stator ground. Re-Test the above "Ignition side tests" using this stator ground wire. If you get different readings, then you could have a bad frame to engine ground. If wondering, our Ground tests did a little dance. Hence, I plan to install a thick ground cable from our battery "-" to the rear of our frame and from the "-" side of our ignition coil to our engine. These extra ground wires should reduce inconsistent ground readings and create less spikes / dips in our unit's electrical system.


Hope this helps....

I will give it a shot, thanks for the great instructions.

 

Check your PM for more info. Hope this helps as well.... Good luck!!!!

Hello,
My name is Jimi,I was wondering what you found wrong with your 150cc without spark,was it the coil,the cdi box,or something else.I worked on one today with the same problem.
Thank's Jimi
