    transplant question

    Installed 200amp alt, first 1 stock clutch pulley low voltage at idle in drive had to raise idle too much not good. returned, was sent 1 with direct drive pulley. Installed a 1.9 pulley nice at idle. 180 stat, tranny aux cooler.

    When I fired it up there was alot of louder ticking noises sounds like the injectors....
    4g wire to pos batt
    4g from alt bolt to neg bat

    mpg droped like a lead weigh is the car running too cold? needle between 15 and 20 mark. its in operating zone. BOM says more torque.
    does the electrical system need time to adjust to more power.

    any and all responses welcomed.

    as usual thank you

    Check your battery voltage while car is running - should be approx 13.8 to 14 volts. It really should not go beyond 15 volts or you may damage the electronics.
    As for current output (amps) that depends on your electrical systems requirements, ie: if it only needs 10 amps then thats all it needs to put out, if you need 200amps (like when you drain the battery while starting) then it will put that out as well. In either case the voltage should be as above.

    Is it staying at high idle? Just a guess, but may be the ECU is being tricked into thinking the engine is colder than it is, then jacking up the A/F mixture??? I used a lower thermostat on my ZX3 and had problems when it got cold. Quickly changed back to OEM.

    Try resetting the ecu so everything goes back to baseline, the computer should handle the idle and everything else from there..

    +1, my head was else where yesterday. That is most certainly the 1st thing that should be done.

    Disconnect the batteries' negative terminal, turn on headlight switch monentarily, reconnect in 20 minutes. Also, as our ECU is a "learning unit", give it about 150 miles of drive time to relearn and adjust. Don't be timid with the go pedal, once warmed up of course.
