compustar starter problem

I'm no expert by far but from what I've read the tach is the way to go.

Go to www.bulldogsecurity.com and find the wiring diagram for your truck to locate the tach wire.

Just my 2c.

Good luck.

Hello-

I'm also having a problem which I am almost certain is a bad brain.  I have everything working except two things, one is the RPS.  No matter how hard I tap on the glass high frequency and all, nothing happens.  The LED keeps blinking it never goes soid, and I never get a page.  More important though, the system never attempts to start the car.  I have programmed tach, and all is well with the ACC1, ACC2, and IGN, but the relay on the board never clicks, and there is no voltage coming down the yellow wire.  This system is install in a 2001 Pathfinder.  It is a CM3000A v.3 brain.  Has anyone ever heard of this problem?

Thanks in advance,

Spencer

If all else fails run off the injector instead and make sure that you flip the dipswitch back over to ON position for TACH sensing.

Do you have the RPS programmed ON ? YOu can turn this ON & OFF via the remoet control. If you have the 2 way remote control you will see a little icon of a phone on the windshield to let you know that this function is ON.

The LED is suppose to be blinking all the time when armed and OFF when disarmed.

Did you cut the jumper wire on the CPU ( GREEN / WHITE ). Also, ensure that you have both starter wires hooked up & also the Immobilizer module is operating proerply with the STATUS output wire from the Compustar is outputting a (-) signal.

Do you mean the YELLOW/BLACK wire ? Also, there's not suppose to be voltage on this wire as it's an AC signal. How are you testing this connection with your DMM ?

• Try turning on-off your RPS from the remote control and also see if you can unplug the RPS sensor from the unit and replug it in.
• As far as the pager system goes, this sounds lik a bad antenna to me. Bring it back to the place that you had it installed and purchased through and get them to give you a new antenna and maybe even a new remote control. The Compustar's have a lifetime waranty if installed and purchased through an authorized dealer.
• As far as the YELLOW wire, that is the starter wire ( YELLOW ) in the CN! harness ) I thought you were referring to the YELLOW/BLACK wire in the CN3 harness for the tach signal. When you try to remote start the vehicle does the IGN and ACC's turn on ? Where did you have the system grounded to and also do both constant wires on the CN1 harness have 12 volts  at the plug after the fuses ??
