I have had no luck getting my charging system figured out so it looks like I'll either be leaving the car at home or driving on battery power. (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif) Anybody have a rough guess as to how far a fully charged battery will take you? No lights, stereo or accesories running.

my car has no alternator. I keep her charged before an event and the battery lasts the whole weekend. That would be numerous starts, about 2 hours running time, etc.

I do have a big 34 optima so that helps. If you end up needing lights and running the stereo, blower, etc. You may have a problem.

You might consider keeping an extra battery in the trunk that is fully charged and ready to go. Get a cheap one at flaps if you don't want to spend the $$$ on a good second battery.

You can make it, charge the battery before leaving and get it there. We can figure it out there. I will bring some spare parts like an alternator, relay board with VR and stuff like that. Just get it there.

I drove a 2002 tahoe over 300 (5hrs)miles with just the battery. It surprized me that it would go that far running the fuel injection and fuel pump.

You can drive a carbuerated car with mechanical fuel pump for a very long distance on battery alone (since you are only powering the ignition). A car with fuel injection and high-pressure fuel pump will run down the battery in a much shorter distance. My Dad had the alternator fail in his 300z while on a road trip and he was only able to make it about 20 miles. No accessories running - just the engine controls, ignition, and fuel pump. You can still run a carbed engine when the battery voltage is down to say 9 volts or so, but most fuel injection won't work at lowered voltages.

Just read Bob's post about the '02 Tahoe. Cool. That's a long way indeed.

In a teener, with a fully charged battery, from Tucson, AZ to 20 miles outside Blythe, CA with a stop in Scottsdale for attempted repairs. A battery pack will then carry you from Blythe to Beaumont, CA. Daylight running.

With a fully charged new battery, you can go from Beaumont, CA to Riverside at night by running w/o headlights in traffic when you are able. It will be dead when you arrive at Riverside.

About 250 miles, day time, no lights. The engine will quit when the volt guage indicated about 9.5 volts.

Okay then, I'm driving it. (IMG:http://www.914world.com/bbs2/html/emoticons/monkeydance.gif) I'll grab an extra battery just in case but damn I hope I can sort it out before then. (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif) Oh yeah, took it to a guy here in town who has a 6 conversion and a 70, 1.7 who thinks it is either the relay board or the main harness?

Allan,

About $60 at Harbor Freight for a battery pack. Charges on 110 VAC plugged into a hotel outlet. Clip it on the dead battery, lay it on the engine, close the engine hatch and no one knows (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

I made it from Nashville to Jacksonville, about 600 miles, on a dead alternator one time. I didn't know it was dead, so I thought it was vapor lock causing it to die when it wasn't getting fuel. I would let it sit for a while, then it would start. I decided to drive home at night, when it was cooler, and actually made it home, with the headlights on. It wasn't til later that I discovered the alt. was bad. (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif)

Clay was able to drive home from Oklahoma (I think it was??) to Dallas with a nonfunctioning alternator. Daylight only, as everyone says. I think it was 5-6 hours each day for 2 days? He had bought a second battery and a charger, just in case--but he didn't need the extra. Just recharge the Optima overnight, and it was good for another 5-6 hours.

I know that you can discharge the battery to the point where it will not start the car, and then you can drive for another ~35 minutes with no alternator. As long as you don't use any lights. Like brake lights. (Damn thing died 6 blocks from home; just too far to push! But still, got me from Candlestick to Sunnyvale after I push-started it.)

I also know that points are much more tolerant of low-voltage situations than Crane/Allison optical ignitions. Not sure about Hall-effect gizmos, but the Allison one I have starts cutting out once system voltage drops below about 10-11V. (IMG:http://www.914world.com/bbs2/html/emoticons/sad.gif) The points that were in it in the above Candlestick->Sunnyvale trek worked up until the FI quit when system voltage dropped below about 7.5-8V.

hmmm....I lost an alt belt on my 1st 914 years ago, drove home at night (with lights on of course)....car started to run like cr@p and started to smoke and I thought I actually overheated the motor...not sure if it went lean or what, but it scared the cr@p out of me...wouldn't start back up once it died and with jumper cables until the next day when it cooled off.......

Yeah, and looks like 70 years... (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif) but you had a battery, and beer.
