Dumb Electrical question so I will start simple...Merc XR6 2.5

[22R]

Is it common for a modified HiPo motor to have the voltage regulators there but none of the wires plugged into anything ? In other words just a mount for the solenoid plate is the only purpose. Let's start with that and see what I get.

Thanks,

My thinking if you didnt use v reg would put too much in batt and cause more woes

A lot of guys don’t run the regs. on 16 amp systems that are running electric fuel pumps, efi, or many electrics in boat to eliminate a problematic area, and its hard to overcharge a battery with only 16 amps unless it has very few consumers. (That is if it 16, being wasn’t stated, just guessing from the Hi-po remark). But has to have at least a rectifier.

[rgsauger]

Totally depends if 9/16 amp or 40. Must have a rectifier to get from ac to dc. Voltage reg is never a bad idea but not always needed

[FORBESAUTO]

Just to clarify if it’s a 40, gotta have em

I appreciate the responses guys....now for the rest of the story. So I have a 1992 Merc XR6 on a Allison XB2002 that i have owned for 20 years. The motor was modded by Dwayne Roberie before I bought it. It has a Holley Red electric fuel pump that runs when key is on. Is there a way to tell what AMP stator you have ? In the 20 years I have had it the only thing done to the motor was a new stator and switch boxes around 2001-2002 by Simon Outboards locally. It has run and run and never a motor issue ( I joke that Lexus must have built it). I upgraded my driver console and needed to fill a extra hole so I put a Volt gauge in it. I have never paid attention to it much off idle but the other day while I was plowing I noticed it was reading like 16-17 volts and I thought that seems high and odd so off to the net to research and I found a lot of interesting stuff about the clear regs vs the newer black fused ones and etc. So I figured I must have a regulator going bad. I pull my cover and notice that mine are not hooked up 5 wires coming out of each going to nothing. Knowing the motor was modded I start thinking maybe the voltage has always been like this and I never noticed it. The XR6 has run so good for so long I am getting skeptical that it can continue so I think I may be trying to solve a problem that does not exist but I figured here on S&F I would get some good answers. I assume the stator must be a 16 amp and the Tach is tied to the rectifier to drive it. Again this may have been a dumb question but I have not had any issues in so long I just was wigged out by the volt reading and I also want to notice next time out what my Garmin is reading on voltage to verify the analog gauge.

Thanks,

Being you said “each of them” indicates there’s two regs. And if ya getting 16-17 volts running a Holley and a garmin, gonna say ya got a 40 amp. 16 amp will only have 2 yellow wires, 40 will have 4. Either way that’s too many volts and needs to be regulated. If ya need any help, give me a shout and we’ll help ya get straightened out.

Just throwing this out there, there isn’t by any chance another set of regs on it, where it could have been upgraded or changed over to a different style and the old regulators just where not removed by any chance? Where’s your yellow wires from the stator going/hooked to?

I will get some pics and check it later today or tomorrow when I am home. I appreciate your help.

I’m thinking if Simon was the last one to fool the stator, he didn’t just bypass 40 amp regulators, he’s got sumpton else going on. He knows what’s going on.

Follow the yellow stator leads to where ever they connect, if they are on a small black plastic box with 3 terminals with hooked up to a grey and red wire. Pretty sure he converted it to 16amp and just left the regulators on the coil bracket.

Winner Winner !! Found just as you described. Now if when I compare the volt reading from my Garmin to the analog gauge if the volts are really 16-17 range is that a problem and how could it be if it has run this well for 20 years and no battery issues ???? I will try to add pics. I appreciate everyones input. i don't know why these damm pics are sideways Arghh

[XstreamVking]

I used to run my dash lights and nav lights to burn off some volts. Would stay at 14-15. 16 amp w/rectifier. Way back then would have to add water to batt after every run.

if ya talkin' 'bout tha little square thing above tha switch boxes then ya a little off.. not a regulator its a rectifier.. something ya gotta have with a 16 amp system..... a 40 amp will not have that.

leavin' tha two reg/rec. mounted is a good way ta "store 'em" in case ya wanna ever go back ta a 40..........

a little off on what ? I just stated it was exactly wired as he described whether it is a regulator or rectifier 16 or 40 I am still confused but I assume it has operated like this since I bought it. Sorry if I don’t follow ya take another swipe I graduated from a rural High School ��
