When Riding Tackett creek area last week we stopped at overlook. Turned key off it would not shut off so we finished the day riding. Got back to camp turned key off it shut engine down I started and stopped engine several times worked normal. After about 5 minutes all lights came on including dash lights on its on had pull fuel pump fuse kill engine and breaker for lights. I unplugged dongle box everything went back to normal rode 2 more days still no problems, My question is do I need replace this dongle box still got warranty or is there really any need for this box.
