    Re: Common failures out on the road?

    I didn't bring a spare alternator last year because the MSD had been bullet proof for five years including two previous Drag Weeks. Unfortunatly it uses non-standard mounts.

    Therefore You know what died right?

        I fried an alternator too, after lots of miles and a couple years on it. My car does okay with a standard GM 63amp alternator, but it's noticeable difference from the 105 amp GM unit I normally have in there. Only about 1 in 5 parts stores stock the 105 amp unit I'm using. For some reason the new alternator I got after Drag Week won't energize until like 1700+rpm, then it's just fine at idle and such. My old one had no problem energizing around 1200rpm. It's kinda annoying.

          I've brought a spare fuel pump (A1000) every year since '06 which is a lot of money sitting in a box, and of course I haven't needed it, but cobbling something together with different inlest/outlets and over all size would be painful too.

          Some stuff you can just bypass, like the fancy fan controller I had in '06, it got water logged so I used a relay and SPST switch form a auto parts store along the road near Indy which is still on the car.

          After Jeff's deal, I soemtimes think I should have a spare coil and injector as mine are not over the counter stuff but I haven't need them so far. Knock wood. I also have belts, a rad hose, lots of valve train stuff and spares of the hard to find gaskets.

          And foldy chiars which I never get to use. But one thing that was really useful we bougt in '06 was a chaepie pop-up tent from Wal-Mart. I didn't use a trailer in '06 and '07 and the tent was a great place to put everything that had to come out of the car, which was everything inlcuding duffel bags etc. We ended up with a lot of other folks stuff in the tent from time to time due to rain and worry about some stuff growing legs

            I didn't use my pop up tent after day one =/ It wasn't any trouble packing it so I may bring it again. I brought a spare fuel pump (a junkyard sourced one I had on the car for a couple years prior, still good), a head gasket set, a 4-pin HEI distributor and a set of injectors. The injectors I swapped out the first day, they were bigger injectors that showed up in the mail the day before I left for Drag Week, so the smaller injectors became spares =P The 4-pin HEI was in case I had a complete EFI meltdown (like hooking the battery up backwards kind of thing), I'd be able to drop the 4-pin HEI in, borrow or buy a square bore carb and be on the road again. I'll bring it with me again.

              ...For some reason the new alternator I got after Drag Week won't energize until like 1700+rpm, then it's just fine at idle and such... It's kinda annoying.
              1700 rpm? can a Buick do that? Sorry, I couldn't resist.

              I know a one wire alternator is supposed to be self exiting, but some of them, like yours, need to be revved to energize. So on a cold morning, your oil is like molasses, and you have an unpleasant choice to make: rev the motor right away, picturing in your mind all those expensive valve train parts rubbing against each other with no oil on them. Or let the motor idle on battery power till it warms up, but if you turn on the heater and wipers, the amp guage goes way negative and the lights dim.

              But there is a fix! If your alternator has the little #1 and #2 terminals (most GM's do) you can just hook up a wire from the charging system warning light on the dash to the #1 terminal on the alternator. If your car doesn't have a charge warning light, run a wire from a 12v+ source (that is only on when the ignition is on), thru a small bulb, and to the #1 terminal on the alternator. That little shot of battery supplied electricity wakes that alternator up instantly!

                Ha! and Hmm. Are you talking about the internally regulated alternators? It doesn't have a GEN light (replaced by volt meter), so if I kick 12v to the #1 terminal it'll energize up? I have an unused 12v FIdle output relay, I can use to kick it on. Is the use of the bulb for resistance?

                **Quick check on the TunerStudio, I can set the parameters such that if the voltage is below 12.5v, that it'll kick closed the relay that supplies battery voltage. I'll have to try it out.

                  yes, yes but you need a bulb or a resitor, yes.

                    I have a 194 bulb and socket I'll try out with it. Thanks!

                      Hey Joel, it worked like a champ! I couldn't use the Fidle output I intended because I didn't install the jumper to activate it as +12v on the relay board, but hooked it up to a +12v source on the relay board and the light lights up when I turn the key and goes out when the voltage goes up. Which it does in short order. Thanks!

                        That's great, thanks for keeping me posted. I like sharing a tip, and knowing that it actually worked out.
