I have a 1993 s10 blazer that I have installed this P.O.S connected purple wire first to the tach wire, then it worked about 3 times then the darn thing enages the starter while it's running. I unhooked it from there and connected to the altenator (the wire that has voltage when the motor starts. It says that it can be connected to the tach, oil pressure sendor or voltage. Haven't treid the oil pressure but figure I would get the same eftect. I tested the wire and it is gettin the singal at the brain. Do you or any one have a phone number, email which I can ask some one who deals with these to get some answers. I hate to think that I tossed out my money on someting that I can never use ------------- Mike Thompson

I have exactly the same problem with my carvox alarm/starter. My guess is that the wire that I connected to is not the right one. The tach wire is supposed to give you an AC voltage between up to 6v. If you don't have that kind of signal, then your main module probably doesn't recognize that the engine is running. But if the wire is correct then maybe the unit is not good. I'll try to work on my alarm and will let you know if I could fix it. Would you post your findings too? Thanks. -------------

Let me ask everyone here this, How can you have AC voltage comeing out of the tach signal? And if it requires AC then why does it say that you can use oil pressure or high voltage? I'm thinking that these are just shhh product and going to take it out and my loss, cause I cann't get a us dealer phone number to ask how to fix or get my money back. ------------- Mike Thompson

You may want to check out another posting on the same topic. Someone claims he could fix the problem. Have a look at posting on October 21 under the topic " carvox alarm cant get it to autostart". -------------

Not sure I want to connect to injector, I would rather be able to talk to a dealer about this but my research comes up only with the one in china. I'm thinking of going with a compustar instead and try to get the ebayer to take it back. ------------- Mike Thompson

Ok Thank you for clearing that up for me. I did some more reading in my lack of a manual, it states in there that can be connected to fuel injector wiring. But I never tired the oil pressure, my truck has a oil pressure gauge which I think might not work that way. Do you know if the brain is self learning, if so what do you have to do to make it learn?

just went and tried to make this thing work again. NOPE got going to work, tried both injector wires, one hade ac voltage at 6 voltages and the meter would should it going from 0 to 6 AC volts. tried rapping the wire around the high tension coil wire 5 times just like in the manaul, showed ac volts at the purple white wire at the brain same shhh.

Ok here's my newiest idea and last chance at installing this type. I am going to install a relay in the purple wire that turns the starter over. I'm going to wire the relay so that when the motor is not running it will make the purple wire connect and have a power wire when the motor starts break the connection in the relay. It would more or less be like a anti grind relay like found on compustars. Any body here think that this won't work please post and why not. I have tryied everything on this thing and conn't make it function right. Also what is a bypass do? ------------- Mike Thompson
