First things first
Troubleshooting the cutting off/not restarting issue.
I adjusted the timing by vacuum reading. I adjusted it until I got the highest vacuum reading, then backed off a little bit. I still only have 10# of vacuum. The miss came back when I did this.
Next, I tested the coil using a method off of WillysMJeeps website. The coil tested out fine cold.
I took a test drive of about 10 miles or so to get her good and hot – there wasn’t any more power than before, so I moved the timing back until the miss was gone.
Then I tested the coil while it was hot – it tested fine then too.
I was going to check my rear differential, but I couldn’t get the pinion nut off – I guess the rear diff needs work, not just a loose pinion nut, because it was definitely tight – the impact wouldn’t take it off.
I checked the generator output – it is making 25v at idle, and 25,2v at ~3000rpm – not good. It is keeping the batteries charged, but it is also supposed to be 27-29v @ 3000rpm. I am trying to figure out why I keep blowing headlights, and this is one of the possibilities – the generator putting out too much voltage. I disconnected the battery and pulled the cover off of the regulator. I was hoping that it was something obvious – the points weren’t stuck, but I ran a points file between them anyway – for good measure. I buttoned it up and checked again – no change. I guess I’ll have to do some adjustment on it after I do some more reading about the procedure.
While I was working with the generator, I decided to try to troubleshoot where the generator was vibrating against the engine. I looked all around it with a flashlight and couldn’t see anywhere where it might be touching. Then I tried reaching all around it to see if I could feel anything – no dice + it was a little hot to the touch. Then I took a scrap piece of wood and started wedging it in different areas to see what helped the most – this is what I cam up with. It is wedged between the oil fill tube and the generator.
I did figure out that she won’t start back up after you let her die. If you rev her back up when she starts to die, she will run another few minutes before she does it again. If you cut the ignition off, she will start back up.
Another test drive
I got in her to go for another ride and she wouldn’t start! This time I decided to hold the throttle down on the floor while cranking – she fired up with a little smoke!
I took her out for another test drive of about 10 miles and to take my Step Dad and his grandson (and Jordan, my daughter) for a ride. Near the end of the drive, about a mile from the house, I hit a bump and both front tires started wobbling so bad I had to slam on brakes! I pulled into a side road because I thought that something had come loose. After a fairly thorough check of the steering linkage, I decided that it would be safe enough to drive – slowly – home. I drove back up the same road, hitting the same bumps, albeit a little slower, and it didn’t happen again. Daniel took some video with his phone, so I’ll post it up here when he gets it uploaded or gets it to me.
When I got back in the shop, I pushed and pulled on the top of the tire and it feels like the bearings are loose! I don’t see how that could happen! I guess it will be the next week before I can pull the front end apart to find out, because I go back to work tomorrow!
I did good this week – I put 50 miles on her and fixed a few problems. I do have a bunch of oil leaks to fix (front and rear differentials, rear transfer case seal, and front engine leak), front end problems now, and a fuel problem (cutting off/hard starting).
Oh yeah, here’s the pic of the field modification – seat hold down device installed yesterday. It works well.
