2000 es450 neutral and reverse lights on

Recommended Posts

Hi all

A es 450 year 2000 neutral and reverse lights on -- for gear position.  From reading other posts I'm thinking wiring faults.  

And help appreciated.  

Thanks Mully

could be a bad gear position switch ?, could be a bad angle sensor ?. another reason i hate es models, nothing but trouble from them. can also be a bad c.d.i..

FYI there is also a fuse that will blow and make both the Reverse and Neutral lights come on at the same time

Dont remember which one right off, but its worth a check for a quick fix

Found that fuse , it's a 30amp just behind the other fuses and it was blown.  Replaced it and all working correctly now. Thanks so much for all help.  Only thing on my mind is why did it blow ????

Glad it helped, most time I find that fuse blows when someone tries to jump start it with jumper cables and puts them on backwards or installs the battery momentarily backward

Either that, or a short from positive to ground while working on machine without unhooking battery

You might want to make sure your voltage regulator is working properly as well, as I have seen a few that were shorted blow that fuse

Could have been something else, but its rare to see one that keeps blowing -so I would think you are good to go

See you around,

Noticed a few tails sticking from positive lead at battery connection, thinking they could have touched bracket over battery,  fingers crossed thanks for input.Found that fuse , it's a 30amp just behind the other fuses and it was blown.  Replaced it and all working correctly now.

Yeah, chances are the 01's both have shot Hondamatics if they ended up at Catfish's place.
