Re: Emergency
Kinda sounds like a timing issue. Was it running good before it broke down? HEI or points ignition?

Re: Emergency
You didn't get any water some how on the distributor? Mine acted like that after I washed out the engine compartment and all I had to do is remove the distributor cap, take a paper towel and dry it out. After I did that it fired right up.

Re: Emergency
Last time I fought an issue like this it was a combination of incorrect plug gaps and the timing being way off on a truck I'd just bought. Unless the retainer bolt is loose, I doubt your timing just changed while driving it. If you've been cranking it for very long to try to get it started, the battery may be too low now as well.

Re: Emergency
So what exactly happened? Were you just driving along and it quit? Or do you go someplace and now it won't start to leave? Was it an active failure like a bang or pop then quit or maybe a sputter down? Are the plug wires secure at the plugs?
Had a total beater timing chain jump in stop and go traffic.

Re: Emergency
When I left my mother's,house I had a slight miss fire at about 1500 rpm. As I was driving I went to use my turn signals and nothing happend. While coasting I put the truck in N and revved it and did not have turn signals still. As i continued driving th lights got dimmer and dimmer. If I shut the lights off it would stop back firing. At this point the engine was missing in all rpms and the light we really dime. As I was going to a red light it just shut down. I am having it towed to my buudys shop since I don't have time to work on it as I am at my dads and I leave for my mothers tomorrow night.

Re: Emergency
Could be a problem with the voltage regulator or alternator? Sounds like it was only partially charging and you were gradually draining the battery down until you didn't have enough spark to fire at the plugs.

Re: Emergency
concur - bad alt would be my guess, no charge to batt. symptoms sound like it's dead. A jump might get you home if someone will stop. If you can get it running (after a jump) - if a screwdriver or something metal will attract to the back center of the alternator, that's a good sign. If no magnetic pull, alternator (and/or volt reg) on the fritz. Can you call a tow truck? 411 for a tow?

If you need to replace the alternator then get a 12 SI internal voltage regulator alternator and eliminate the old external regulator. Even if the battery is bad the alternator should have kept the engine and lights running.

Re: Emergency
if you're referring to the chassis ground that is bolted to the firewall, no - that's probably not your problem, but if you have a screwdriver, screw it to something.
Voltage regulator should have the following: Red wire goes to alternator "B" terminal Purple (or blue) wire goes to alternator "F" terminal White wire goes to alternator "R" terminal Brown wire goes to firewall fues block plug Altarnator should have the following: the 3 things noted above + black (or any color) should go to ground. Also, the red wire that goes to the voltage reg also should go to the battery Probably not much help at 1150pm - hope you have a flashlight. Standing by...

Re: Emergency
Btw, u never asnwered the rain question - have you hit any water? Heavy rain?
If yes - possibly a bad distributor cap - hairline cracked, etc. |

Re: Emergency
Your regulator is mounted on little rubber washers and needs to be grounded to the radiator shroud and also to the back of the alternator for it to work correctly. The green wire might have done this but usually a black wire is used for the ground wire. Those little electrons don't really care what coat they're wearing.
Alternator ground. regulator mount. The small wire on the right edge is the ground. Here is the electrical diagram. The ground wire is on the left edge of the diagram and runs to the bottom and back up to the alternator.

Re: Emergency
I couldn't help but thinking after reading this post. Where else is a guy going to turn to at 12:00 midnight for help when he is broke down and stranded and have the best of the best mechanical and electrical gurus answer your call for help at no charge at all. That's why I've enjoyed this site from day one. Nice work guys

Re: Emergency
Don't forget,there is a hotline for help.It's run by the BB and staffed by whoever is close and can help.Members have been helped in many ways.One military member even had some fellow BB members help with an engine swap and getting him back on the road to keep him from beoing late to his post.

Re: Emergency
Thanks for the help, I got the battery charged and had another guy look at it (see what I missed) and it looks like the black ground wire is gone in the pic VetteVet posted. when I was talking to the one guy he asked if I had to polarize the system. I said I did not know. Do I need to polarize the system
Also I wanted to thank all of you for your help, Once I get my truck running I am defiantly becoming a paying board member
