Been posting on other threads of folks who have had charging problems, which is what I am having...

This is a recent 'new to me' truck.
1980 4x4 HiLux
20R, 4spd

Alt is good.
Voltage regulator is good - just put in a new one, thought that was the problem.
Battery is new.

Digging through the wires to find what might be he issue and apparently I do not have a Charge Lamp Relay. Not in any location suggested. I am at a loss as to what to do next.

 

I've been posting on other threads trying to get help here.

I'm going to go a different route than what most folks seem to be going, and trying to put a stock type alt from an '80 Land Cruiser in my '80 HiLux Pickup.

I posted some in this thread: https://www.yotatech.com/forums/f114.../#post52274366

 

Is your battery getting charged when the motor is running? You never actually specified a problem, at least not in this thread. I put a volt meter on the battery with motor off, then with the motor idling (should be higher), then with it revved. I like to see 14V or so with the motor revved.

 

Yep, just refer to the link in the post above yours...

 

Posted this yesterday in the 'What Alt fits a '79' thread, figured I should add it here too...

Just finished with the land cruiser alternator swap out.

Success!!!

I now get 14.45 VDC at the battery.
It does need to be goosed to start charging. I cut into the ignition wire at the plug that connects the original voltage regulator plug. Now for clean up, and I'll do a write up tomorrow...

One thing I need to figure out, even after looking through the forums (too many possibilities) is a fusible link for the alt to batt wire... Just a 55 amp alt using 6ga wire. Not sure what size link to use, or maybe just get a HD fuse holder and put in a ? amp fuse... Could use some suggestions...

 

So, some new info from Msane99 (Thanks Mike!) shows that the trucks with the 40 amp Alternator do not have the relay... SO maybe my truck never had it?

No matter, I did the Land Cruiser Alt swap/upgrade and it works great...
Will do the write up for it soon, I promise!
