Hi I'm installing my first Alarm/remote start system in my 1990 GMC K1500 regular cab pick up I have power locks and all that good stuff. Here is my problem I have it all hooked up doors lock and unlock fine alarm works my problem i swith the auto start I have the Tach wire hooked up right on the coil and tested it with a tach meter. but when that connector is pluged in the unit and turn the key to the on/run it's fine but when I go to start my truck with the key the circut that that the connector is pluged into where the tach is going into the unit starts to smoke and burn up only when you crank the truck over but when you unplug the connector the tach input it's fine. now I followed the book on where all the wires go and looks right to me and this is the second unit now I had got a few of these Designtech 20092. Any idea's on what I'm doing wrong or hooked up wrong? Not sure if it makes any difference but the truck dosn't have a tach in the dash from factory but I know I have the right wire on the coil white wire and have tested it at the coil and right at the connect where it plugs into the unit.

I didn't see that model on their website,I was trying to lookup the manual.You need to say what the wire colors are that your using from the command start and the wire colors that you are connecting them to on the vehicle.What does the car do when you try to remote start it?

This is a Ready Start two-way remote car starter with keyless entry and auto security system #20092 I'm useing the White wire on the Coil and the green wire on the three wire connector on the unit that says hook up to the rpm. and I have even tested this wire at the coil with a tach and an with a multimeter on AC and it's the work then I tested it at the connector inside the truck and works again. but when the connector is pluged into the unit and you go to just start the truck with the key it's fine when in the run postion but when you go to start it starts to smoke the unit when the tach connector is pluged into and this is the second unit I have tired now. I went over all the wires and all seems to be right. it smoked to when I tired to remote start it. With the RPM connector not hooked up everything else works fine with the alarm and when you remote start it will start but of as would happen the starter keeps running till you hit the brake. prdjr165 wrote:

is there anyway to program it to start without the tach sensing hooked up?Most other remote starts can start using the tachless method.

If I remember correctly,designtech models use dip switches for tach or no tach,again,check out the manual if you have one.

Yes I have the manual. To be honest I don't know what a dip switch is. The manual says there is a Tach mode and an alternator mode but it dosn't say how to hook the altenator mode. prdjr165 wrote:

I'd like to help,But without access to the manual I can't do very much.The manual should show the dip switches and the process needed to program the unit to tachless or voltage mode.

I would also need the manuel to figure this out. Try this... unhook the tack wire from the unit and while the engine is cranking check and see what you have coming out of the tack prong on the unit (-,+, AC or Dc).

Yes I have tested the AC coming out of the tach wire before I forgot the exact numbers but as you rev the truck the AC voltage goes up just like a tech would. and I hooked a tach up to the wire and that works fine. I can NOT leave the connector plugged into the unit when you crank it starts to smoke the unit and I tried to plug it in wile the truck was running and I programmed the unit to be in tach mode and it stalled the truck and smoked. the unit again. but when I mean smoked the diodes on the circuit board started to smoke but I didn't let them complete fry like the first unit. So I programmed the unit to alternator mode and it's working fine now. but I can't understand why it keeps smoking I know I have the right wire off the coil (white) looked in the service manual and I'm using the Green wire on the unit that is for the rpm signal. I'm really stumped on this one. Craig3708 wrote:
