I installed a prestige aps-786t on a friends Altima the other day and I ran into a problem. If you remote start the car it works perfectly, but when you put the key in and turn it to the run position (not start) the starter spins for a fraction of a second and it grinds. If the car is off and you put the key in and turn, it won't grind and everything is normal. It only happens when the car is running with the remote starter. I wonder where the short pulse is coming from when you turn the key with car running of the unit. And it happens as soon as the switch goes from acc to run and it will do it if you go all the way to start but we are not turning the switch that far. I can fix it by using the (-) ign 3 output from the unit to power the starter interrupt relay while the car is running with unit. But I'll like to know what is causing the problem.

Did you hook up the ign sense wire up to the hot while cranking wire or secondary ign wire? that could be your problem.

Nothing is impossible!
Do it right the first time or don't do it at all.

No everything is connected right. I've installed 10 to 15 of this units on different cars including previous years Altimas and I've never run into this problem.

I've had the same problem on a few older Nissans. (I install Audiovox product as well, so I'm familiar with that 786T; nice piece.)
Anyway, did you just jump the two starter wires together, instead of triggering the other one with a relay? I'm not sure exactly why, but that is usually what is causing the problem.
Two solutions, one being faster and easier than the other:
1. Power up the two starter wires separately, using the Audiovox's BLACK / YELLOW "pulse during crank" output to trigger a relay for the second starter wire.
2. Use a diode between the two starter wires. It's a trial-and-error job to figure out which way the diode has to go, because you don't know which starter wire is causing the problem.
A. Take car apart, remote-start the engine, leave it running.
B. Disconnect your RS' starter wire from the car. Leave the car's two starter wires exposed.
C. Place each end of a diode....one end on each of the car's two starter wires. Turn the key to Run and see if it grinds......if it still grinds, turn the diode around the other way.
D. Now, connect the starter output from the RS to just ONE of the car's starter wires, leaving the diode in place.................the idea is that you're powering up one of the car's starter wires directly, and the other one through the diode.
E. Test every possible sceanario for grinding, also make sure the remote start still starts the car, then make the connections permanent and put the car back together.

Yeap I did jump the wires together. I'll try the diode on the second starter wire and still connect the ign 3 to the starter interrupt for the anti-grind. Also on the Bulldog wirring diagram it says to use a relay to isolate the acc wire from the switch during remote start. I didn't use it. Could that be the problem? It was too cold the other day to keep working on that car 5 degrees outside with a windchill of 6 below.

Run you wire like this. Problem solved. ------------- Be careful whose advice you buy, but be patient with those who supply it.

guys do NOT USE A DIODE to separate the ign wires..... use a relay as stated. diodes heat up very quickly..... and they will def be heating up in this scenario....unles you use one massive diode...

This problem is common on Altima's. Use a relay to install a anti-grind circuit. Hook terminal #86 to ignition and terminal #85 to the remote starter's ground out when running. Cut the main starter wire in the ignition harness. Wire the vehicle side of the cut starter wire to terminal #30. The other side of the cut wire (key side) goes to terminal # 87a. The last terminal # 87 goes to the remote starter's starter wire. This will eliminate the grind and allows you to turn the key too far and not grind the starter when using the key to take over the car from the remote start.

I used the 3rd ing wire to power the starter interrupt and put a diode on the second starter wire. It worked like a charm, and now it has an anti-grind circuit.
