Battery Over Charging...

[Mike Ramos]

Hello Fellow FJ Owners,

On the way back from the Colorado Rally, the "useless no reason to have..." on board volt meter indicated an over charging condition, potentially damaging the lithium battery. 

Having installed a new voltage regulator some time before the major engine rebuild by RPM (about 20K miles since rebuild), it was doubtful the regulator was the culprit.  At the same time the regulator was replaced, a new ignition switch was installed so any voltage drop would not be through worn contacts.  The infamous alternator connection which is prone to overheating had also been replaced at the same time as the regulator & ignition switch.

Upon returning home, using the multi-meter it was determined that the voltage sensing wire (routed through the harness and switch) indicated just over a volt less than when voltage was measured directly from the battery. 

So I ordered a relay and connector socket from RPM and wired it to the alternator voltage sensing wire.  The alternator output voltage returned to a reasonable 14.4 to 14.5 volts.

The relay was mounted on the left side of the battery box.  The sensing wire now energizes the relay and all is well.  Just passing on a simple fix to a potentially expensive [over charging] problem.

Ride safe.

Quite the contrary Mike. You can never monitor too many things, especially for the places and distances you ride. Sounds like you dodged a bullet there, well done on the fix.

Very creative Ray.

Here is the one I've used for the last 40 years...




Endlessly adjustable in all directions, compact (folds up and can be stored in a drawer) cheap to buy, multipurpose, portable, quick set up time, rock solid, can be inverted, universal (fits any carbies) self compensates for wear, durable (will last for decades) has a special mode for chewed up screw removal, can be used for tapping out float pins, the handle is designed to hold open the butterflies while reconnecting the cables, can be used to crimp fuel lines for tank removal.......

Noel,  Where would you like your above post moved to?

I tried to ask you via PM but you've blocked my PM's to you.

Sorry Pat, I didn't realise you were blocked. You can delete it. I didn't realise I had put it here until I read your post this morning, it was intended for somewhere else.

No worries, I can move it to wherever you want, if you wish.

It needs to go in the tools section!

Another great idea!

The first one, second one or both?

Yea, it would be a shame to delete it..... That Noel guy is a clever rascal....
