Nigel mine does that too, has for years. I chased it around for years and just gave up on it. Maybe cougar is on to something, if you get it fixed let me know what you did to fix it.

Will do BRD, mine always has to, but not so erratic as it does now. I tried the "wiggle" test on the ignition switch, didn't make any difference.

The "wiggle" test won't show the bad contacts. 89-91, most of the power went through the ignition switch. The contacts weren't made to handle that much load. Starting in 92, they started moving the bulk of the load onto relays. The ignition switch only had to handle the load of the relay coils then. Moving other big load items like the blower motor and power windows to relays further reduces the load.

Carrying on with my 47RH swap. I had a shop extend the transfer case shift bracket to get the shifter back in its proper place. For the rod, I got a couple large rod ends and threaded rod. I'll put boots on the rod ends to keep grease in them and protect them from the elements.

I used a '91CTD in the wifes Ramcharger and had charging issues with the factory chrome VR on the firewall, they'd work for a while and fail and at around $40 it was getting expensive. Tossed the 1960's era VR and replaced it with a tiny NipponDenso VR that you wire up yourself inside the alternator, problem solved. It keeps a constant 14.2 volts regardless of throttle.

Here's a link to installation

On another charging issue in my stock '92, I noticed low charging on the gauge and the slow loss of power starting up....assumed the alt died and replaced it with $240 Bosch which also showed no charge(I don't believe the Napa tech had the correct wiring to test it)and luckily I got my money back and went with a cheaper ND around $160ish but still had no charging. I believe a second electrical issue popped up, I think it was the tach quit and it threw a code for the Crank Position Sensor. Replaced the CPS and all is well, charging and tach. Point is I bought 2 of those ND internal VR's intending to swap and upgrade but they only work on the earlier 1st Gens with the Chrome VR, I'm happy to send it to you if you want to give it a try, they will just collect dust here.


Swapped hydro boost brakes into the crew cab 2 years ago and the brakes have been perfect ever since, this truck had eaten around 40 boosters and M/C's over15 years. She stops like a brand new truck and hasn't had a single issue, probably saved a couple accidents from happening as well, she'll literally throw your dog out the front windshield if you jam on'em...

Love to see pics of that swap. Would love to do one with my ageing '79 Ramcharger

I didn't take as many pics this time, she bolted up pretty easy. Found a W250 front axle in North Fl for a grand and a donor D250 farm truck for $1600, I wished I had found a donor in better shape, the instrument cluster was crumbling just putting it in, I think 3 screws are holding it together. Mechanically she's perfect, only issue was charging, replaced a freeze plug and WPump. My wife drives it 3 miles to work and it ain't even warmed up when she gets there. We evacuated with it for H Irma for its 1st trip outta town, 150 miles on 5 gallons! it barely got 10 mpg as a gasser.









Still need to sort out the a/c and the hurricane lifted the clear coat, while the CCab is down due to fan bracket the D250 acquired an electrical short and was down for a week because we couldn't find a wiring diagram because the internet was down, had to use the Ramcharger to shuttle crew and chainsaws clearing trees, she's pretty but she's all Cummins and loves to work. Thankfully we found the short near the transmission, probably pulled the wires driving over tree branches cleaning up, the 250 pretty much ran all day hauling trees like a wheelbarrel. Alls good just hoping to find that bracket soon...

The regulator, weather stand alone or in the PCM controls output by varying resistance to ground through the field winding. If there is a higher than allowable resistance in the wire going back to the regulator the the voltage will drop off. On the flip side, if you have a low voltage going into the regulator (wire resistance or worn ignition switch) it will drive the output high.
