This one is a real head-scratcher! My 2000 300 2x4 always starts instantly. If the temp. is 60 deg. or above it runs perfectly. If the temp. is between 50 and 60 deg. it will start, but the rev limiter kicks in at low rpm causing severe misfiring, but turning on the lights or activating the brakelight causes it to return to running normally. At some point both headlights blew simultaneously leaving only the taillight working. Now between 50 and 60 deg. it will run w/taillight on or stoplight actuated. Below 40 deg. it will only run with both the tail and stoplight on. After it warms up for a while it will then run normally without the lights on and the rev limiter only kicks in at high rpm like it's supposed to. HELP!!

hey not sure if you got any help from anyone but that is an extremely strange issue. and i would start chasing wires if i were you. look at all grounds clean the connections etc etc. but otherwise check out www.arcticchat.com. great site great people alot of very knowledgable people. this is a good site but its a litle slow with getting a response and that site is very busy. check it out im sure someone can help ya.

 

Thanks I'll try that. I haven't started doing any tests yet, but I suspect it has to be a problem with either the Stator, voltage regulator or the CDI box. All expensive items!
