On 'Black Betty' ('78 CJ 5 w/360) I was struggling to keep her cool so one of several cooling mods I did was use a Flowkooler water pump. A feature of this pump, unlike many others is there's bearing on both ends of the shaft, leading to longer life of the water pump, just my 2 cents.

I'd like to find a front skid plate to protect my lower radiator and steering box al la '70's Con-fer skidplates.

Thanks guys! and I hope all goes well Terry!

Hi gang, long time. As what happens to all of us, "life is what goes on when we're busy making other plans". 'Black Betty' for another season, seems to be in good nick One hiccup was over the winter the trickle charger was set to Motor Sport instead of Automotive. Since my last login I've...

I sure hope you don't fall into a temperature conundrum. When I was correcting a botched e fan install on 'Black Betty' a few years ago I found that I'd opened up a can o worms response wise.

That's where mine is set at JPN, it doesn't seem safe to me.

I took BB out for a test drive today and the temperature was steady at 190* :verry-happy:

Hi Gang, Now that I have my e fans under control again I noticed that the vacuum nipple is hovering dangerously close and just above the power steering belt. Can someone give me the rundown on how to clock the distributor in it correct position? Thanks and a lift of the lynch lid. Gus

Man, I couldn't believe what a task it would be to find some scrap foam rubber, ultimately I had to hack up some children's toys but I got it all cut to fit and I'm just waiting for the weather to cool down a bit so I can remount the controller case to the inner fender and re~loom all of the...

:verry-happy: Got the new controller spliced in and everything is working now. I haven't hacked the old one out of the circuit yet (I spliced in with solder and 3M heat shrink) So next go I'll remove the old controller and it's wiring and open it up. I'd lay even money some solder came loose...

I got the 70amp relay plug wiring done by the graft I had shown in a previous photo, now onto the controller package. One I get the old controller out I'll disassemble it and see if I can expose the board for a photo.

I thought that perhaps I needed to move the box that contained the pair of controllers (one of which had failed) further away from the Radiator and perhaps it was radiant heat that caused the failure. However, when I idled the motor to operation temp and using the remote thermometer on varied...

Welcome to the forum and Happy Independence Day (I celebrate another one in December given my lineage) Great folks here explore and enjoy!

Edit: It came to me while I was just falling asleep the other day. Check the ground from the Circuit Board of the controller to my ground bus bar. Result: Failure apparently on the board there is a broken ground connection. So no longer a mystery.

I got the new controller and not only is the new style equipped with two fuses that the old one didn't have, the threaded sender connections seem more robust. :D I may get into this tomorrow, it's Jeep season after all.

I understand that as I didn't include photos of the wiring some may suspect that it's a hack job. I just wanted to point out that ALL the wired connections are soldered, and whenever possible I use 3M heat shrink tubing, if not Pico or some other heat shrink. Also all of these circuits are...

I fired up the Jeep today and mowed the lawn~dandelions and let the Jeep idle up to operating temperature. I then adjusted the potentiometer screw for low speed and it began working. I could not get the high speed to work but did verify that the low speed shut off after the motor cooled down...

Thanks again, JPN I'm running out of time this week as I go back to night work tomorrow.

I was looking at the Flex a lite fan controller on Summit and it has the NPT sender that I use and a more robust potentiometer than the Haydens I'm using but the description says Single/Dual fans but the installation .pdf only mentions one fan I wonder if I can split the output to fans on that...

I was able to check the grounds~correct and signal~correct I then jumped power from the control board relay socket to battery I heard the secondary relay click and the fans started working. I did the same on the high speed control board and it worked as well. I think the problem is still on the...
