My Warrior is only a year old, and the CDI unit puked on me. I had a loose battery terminal connection, and sometimes, I would have to wiggle the cable around to get it to start. So my question is, can a loose connection like that cause damage to ignition components?

 

I NEVER PERSONALLY HAD THIS HAPPEN ON A QUAD, BUT I WORK ON CARS FOR A LIVING AND HAVE SEEN ELECTRONIC PARTS GET COOKED FROM BAD GROUNDS & LOOSE CONNECTIONS.

 

Like Klapper says.....Absolutely...any loose conection can cause undo voltage loss and/or spikes. If you have a loose ground or similar connection...the spike will have nowhere to go but through the component. Which could cause failure. I would think that most units have a built in failsafe to protect against such incidents...But since most dealors will not release the internal specs of a CDI box...It is hard to diagnose.

I know that the warrior does have a fuse out back....You did check that right? (I'm sure...I just had to ask)

 

Thanks a ton guys. I just ordered a new CDI unit today for $287.00. I just want to be ABSOLUTELY sure I was ordering what I needed.

 

Ouch!!!! $287 bucks. Is that thru a dealer? I bought a new one for my R for $70 from Service Honda. They are a discount Honda parts place. Look in the back of Dirt Wheels for discount Yamaha parts and try them.

 

i just have one thing to say oooooooooooohhhhh no a cdi box COST!! that sucks i have the org cdi on my 86 4trx250R and pray it don t go i feel for ya
things like that can happen to any of us! hope u can find a good used one maybe place an AD. for one on this site!

 

Unfortunately, Yammie electrics are always more $$ than their Honda conterparts.

There's now a few aftermarket companies making CDI's for some models, but I have yet to find one that works as well as the stocker for the Banshee.
