05 Tacoma with 791XV major problems

I had a 791 XV installed and have had major problems.  The first time I got the truck back the car wouldn't charge, the dealership said an alternator connector was dislodged and a computer connecter was dislodged.  I just got the truck back for the second time from the installer and now the truck has again had its battery die. 

Symptoms:

When the car was starting, last night and this morning, the car started really rough with the key, but fine with the remote start.

When I attempt to start the truck with the key today, it won't start, and when I remove the key it trys to start over and over again, about three times without the key even in it.

What could be draining the battery? or interrupting the alternator?  Also why does the car try to start multiple times when using the key without RS?

I agree with Kgerry, you've given the shop 2 chances to fix what is wrong.

Thats assuming that everything worked correctly before the install.

Anyway for the battery to die repeatedly you have to have an open circuit. The shop should know how to check for this with their DMM. Seeing how you had it installed I would not recommend doing too much on your own. They could come back and claim you have modified the car after install and tell you your on your own. About as far as I would recommend is pulling the fuses on the the main line into the alarm as well as the 2 +12volts wires on the mini relay satellite.

You may have a relay not functioning correctly in the relay satellitte. It's very small, approx 2.5 inches by 4 incehes and will have thick wire runninf from it into the steering column starter wires. See if your power drain stops O/N.

You could ask the shop who specifically installed it. I used to work for a natinal electronics chain and we had a good reputation locally, but 1 or 2 poor installers created a few problems by taking shortcuts and it really hurt our business, No they we're not MECP certified but the shop manager and ass. manager we're. When I was invloved with a few customer problems, I was told " well they're being trained to take the MECP course " or something like that.

Either way take it back to them and have them look at it. I would try and arrange to be present to obersve the troubleshooting process. That way you can post back if you run into more problems with some more detail.

Good Luck

Ok, yesterday (when the battery was dead) I called the shop, and the store manager and shop manager came out.  They jumped the truck and got it running, and disconnected all their equipment, and watched the battery for about a half an hour to see if it drained: It didn't.  After that they hooked everything back up and monitored the battery for another half an hour to see if it drained:  It didn't.

I went and bought a volt meter and took the truck home.  The store manager gave me his cell phone # and told me to call him at 8 with a voltage readout.  I did that and it was at 12.99, this morning it was at about 12.80.  The car started fine and everything seems to be working fine, eventhough we/they didn't find anything wrong...

Is the drain from 12.99 to 12.80 overnight normal?

Last question.  Everything is seemingly working fine, except for one.  The car starts fine (usually) with the remote start, but if I try to just use the key, it starts prety hard.  I usually have to turn it over a few times, for a few seconds to get it to start.  There is a key module installed under the dash.

Any ideas?
