The vss has 2-wires, and generates a four-pulse (4000 pulses per mile) sine-wave (A.C. current) with minimum voltage of 1.8 volts and the signal climbs proportionately with vehicle speed.
I would like to convert the AC sine wave to a DC square wave with a voltage of 0-5 volts (most senors are 0-5 volts on computer equiped cars) so I can connect my innovate LM2 to it so I can record MPH along with the AFR and RPM that the LM2 records. The LM2 has connections for analog input and output. The LM2 already does this through an OBD2 connection but this hot rod has no OBD2 connection as it has no ECM.
This is not something that will be mounted permanently in the car if that helps.

Thanks for all your help guys! ]]>Fri, 03 May 2013 15:27:36 GMThttp://www.chevytalk.org/fusionbb/showtopic.php?tid/296880/http://www.chevytalk.org/fusionbb/showtopic.php?tid/296880/Thu, 02 May 2013 17:46:05 GMThttp://www.chevytalk.org/fusionbb/showtopic.php?tid/296856/http://www.chevytalk.org/fusionbb/showtopic.php?tid/296856/Wed, 01 May 2013 23:02:12 GMThttp://www.chevytalk.org/fusionbb/showtopic.php?tid/296780/http://www.chevytalk.org/fusionbb/showtopic.php?tid/296780/
So far I have replaced: headlight switch, turn signal switch, ignition switch, high-beam switch, re-run all the grounds.

Yet the issue still persists. Any help would be appreciated. ]]>Tue, 30 Apr 2013 03:33:09 GMThttp://www.chevytalk.org/fusionbb/showtopic.php?tid/296702/http://www.chevytalk.org/fusionbb/showtopic.php?tid/296702/
The rear taillights, i have a right rear brake light, and a left rear taillight. I replaced the bulbs, still no change. Car is still using the factory taillight sockets on the new wire harness. The factory blinkers work fine tho, left and right.

The headlights, I pulled the headlight switch, head lights came on. When I hit the high beam switch, sparks shot out of the after market head light switch towards the knob followed by a fee sparks under the dash with a loud pop.

Majority of the wires under the dash coming from fuse box are not used, are wound up and zip tied under dash. This on the '54 sedan that I was having starter issues with.
Thanks in advance,
Dave

Just wondering if there is a way I can use one wire on the temperature sending unit gauge instead of two? Reason why I am asking is because I have three after market gauges for the temp, voltage and oil pressure and the temp gauge only uses one wire. I want to be able to use my cluster dummy lights and my after market gauges.

To my understanding one wire is for hot and the other is for cold.

Thanks in advance.. ]]>Wed, 24 Apr 2013 22:37:40 GMThttp://www.chevytalk.org/fusionbb/showtopic.php?tid/296499/http://www.chevytalk.org/fusionbb/showtopic.php?tid/296499/Tue, 23 Apr 2013 01:46:44 GMThttp://www.chevytalk.org/fusionbb/showtopic.php?tid/296410/http://www.chevytalk.org/fusionbb/showtopic.php?tid/296410/ I have a 64 impala and I recently swapped out my bad 327 motor for a 350 motor and I replaced my engine harness and light harness.
Now when I put my ignition in "ON" position the starter becomes enabled. At first I thought it was my starter so I replaced it and I get the same thing.
My setup is ignition and battery wire to starter, I have one of those high output alternators that has only one terminal and no connectors and I have that hooked up to my battery and harness wire to alternator is hooked up to the alternator.

I guess I am stuck. I have been going over the wiring diagram and everything looks according.
Is there something that I am missing here?
Thanks. ]]>Sun, 21 Apr 2013 10:36:00 GMT
