reg/rectifier

[xp150]

I posted a question about not charging on a 1989 <br />Evinrude XP150 and was told it was the reg/rectifier.I looked in the manual and it did not give me enough info so I have a couple of questions.<br /><br />Does the flywheel have to come off to replace the reg/rectifier?<br /><br />Is there something I should look for that could have blown it or do they just go bad?? Thanks Randy<br /><br />Also I found one for $160, Is that a good price???

Re: reg/rectifier

Yes, you have to remove the flywheel. Sometimes they go bad because its possible to trap air at the top of the block and the reg/rec overheats. There couls be other causes too like loose nuts on the battery. Lose the wingnuts.<br /><br />Make sure the one you found is for a 35 amp system. Both units look the same but the 35 amp reg/rec had a larger red wire. You can use a 35 amp reg/rec on a 10 amp system but not vise versa. You should have the 35 amp system with the vented flywheel.<br /><br />There could be other reasons you arent charging but if you lost the tach too then its most likely the reg/rec.<br /><br />Good luck
