Hello, and thanks for stopping by.

The truck was my late grandfathers. A June of 86 - D150 Royal SE equipped with an ESA 318/ Holley 2280. Has factory air conditioning, cruise control, and 5 speaker AM/FM radio. Haven’t confirmed which transmission or final drive yet. Currently is all stock. My grandfather was the second owner of the truck, having purchased it from a friend with about 13,000 miles on it. When he passed in 2004 as part of his estate it went to my aunt who drove it off and on. When it had some mechanical qualms in 2006 it was parked in the outskirts of the driveway under a shade tree, to be gotten around to. Well, fast forward 14 years and the truck is offered to me. Free, and as it sat. Which of course was ‘not running’.

To present day, I put a fresh battery, fresh gas, topped off the trans fluid, put tires on it, to get it driving and just repairing gremlins as they pop up.

The one that’s got me stumped at the moment is no brake lights, but I’ll get to that another day. (Has been fixed)

Until then, thanks for having me and hope it goes well

 

Wow.... My first thought was: Needs a good bath. My second thought was: HOLY SMOKES that cleaned up NICE!!!

Looks like a great place to start from. Congrats on the truck.

 

nice looking truck. have you checked the fuses? i would start there and then check the bulbs then brake switch.

 

Nice solid truck. On the brake lights, do you have turn signals back there? If not, check the bulbs. If you do, check your fuse and the the wires where they connect to the brake light switch. From the green coating it had, it may just have a little corrosion. Were the brake lights one of the mechanical qualms it had? Do the rest of the lights work?

 

Thanks for the warm welcomes everyone. 😎


No, it has a minor trans leak that is scheduled for repair, front pump seal I believe. Already repaired were voltage regulator, new wiper linkages and motor. clean/rebuilt carb. But still has a stumble that I believe is also trans related or electrical. Needs front suspension refreshed, And it still has a choke circuit issue.

Running lights and turn signals work. It’s just the stop lights that are in-op. I have power at the fuse under the column, but don’t have power at the red and white wires of the SLS.

 

if you got them replacing the front pump seal get them to replace the rear main seal on the engine while they are at it. they always leak. if it doesn't leak now it will once you start enjoying the truck. it could be replaces later but would way easier to replace with the transmission out of the way.

sound like might have a bad brake like switch. should be able to connect the 2 wires to brake light to come on for testing purposes.

 

I’ll be pulling/installing the trans with a local shop doing a once over on it. I was going to replace the rear main while it was out. I’d be crazy not to.

As as far as the brake light deal, I have two pigtails coming off mine (2 wire brake switch, and 4 wire for I assume cruise control so it knows to release when I hit the brake pedal)

it it all tests fine on the multi meter. I have 13.2v at the fuse but nothing at the switch connector. And thus, no power at the rear of the truck. My guess is it’s somewhere in the dash harness, I’m just not good enough at electrical to have dove into it yet because I’m trying to round up proper wiring diagrams. But due to trim level and year seems to be difficult. (Mind you in the meantime I’m digging through the depths of the forum looking for info too)

 

are you sure the brake light fuse is good? it is different from the turn signal one.

 

yeah, I’m pretty sure. I’ll take pictures of what’s there here in a sec.

although, should I start a tech thread so we aren’t trouble shooting in the intro thread?

 

Thats not a bad idea. Then I can close this one so there won't be two conversations going on. Just PM me when you create your new thread. Nice truck BTW. Total score on that one. I love those trucks!
