Granddaughter's 80 quad won't start
 

New to forum and need help. Son said it has been running and starting fine but after sitting maybe a week or two it is dead. The battery is new and fully charged but nothing no clicking no nothing. I checked the fuse and its ok, cleaned battery terminals still nothing. Is there a way to jump the starter to rule it out? what am I missing?

Welcome to the forums. :)
Try pushing the red dot under the right rear fender.

I've done that ,right now I have jumpers on it. Not to be too cheap but is there a way to test the starter relay? Not getting power to starter. Tried jumping it to no avail. I've bypassed the switch on the brake peddle. Tore the key switch apart and couldn't see anything wrong, also the on/off switch. Too many wires in there for me to bypass all for a direct shot at starting. Thanks for the fast reply, I'm open to all..

You can test the starter by applying 12 volts to the wire or directly on the starter.
That start button has been known to fail.

You can test if you are getting power to the relay by removing it and putting a test lamp on the thin wires that go to the plug, one is earth the other live. The starter switch is on the earth side, so only earthed when pressed with brake on and ign switch on.

Thanks guys. Good info, I'll try it.
