Will a 2005 Honda TRX450R 450R 450 R Electrical Voltage Regulator work ok on the same model ATV only a 2001?
Thks  

i have a polaris 700 twin, the battery is new and tested good but the quad will not hold a charge, what could the issue be?  I had read a little about the voltage regulator online but cannot find one for a 2004  

My dad has the same machine.  Has the same problem.  2006 the unit was replaced under warenty, THen again now two years later same problem.  It is like $1000 dollars to fix I was told.  THe part is like $500 and the labor $500.  He runs a winch on his machine which is connected year round. I am convinced it is the winch that is doing it.  I told him to put a fuse near the battery on the pos side of the winch cable to see if it would clear up the problem.  I am convinced because my buddy has a recon with the same prob.  He just charged the battery and un hooked the winch to see what would happen. It has been running stong for a week now.  No problems.  If you have a winch I would try it first.  

if i remember correctly they have the same part number, call your local honda dealer to be sure and ask them in the parts dept.
