    Hye, jsut got a box!

    I am going to pick it up this weekend.....


    some one told me to put elec tape on the fuel injection wires....they
    are hot voltage, and can ground out, and can burn up the car.

    any thing else I should pay attention to?

    I have to drive the car 100 miles to get it back home.....I am gonna
    check fluid before I roll.

    Also, the batt wasn't charging, so the buy I bought it from said, and I
    am gonna bring a ohmmeter to do some and some extra batts just in
    case...

    I have a volt guage, to keep an eye on the batt while driving.....(I
    don't trust the one in the car, it is reading zero....soe just to check
    I am bringing another)

    Where do I hook up the volt guage? across what terms? just pos neg on
    batt? or to somewhere on the alternator....


    thanks for the help

  2. Well, that's a new one on me. However, your 1987 is in the range of Volvos
    with the biodegradable wiring, and if you look at some of the smaller wires
    under the hood you will probably find places the insulation is crumbling
    off. The actual solution is to replace the engine harness, which is a lot
    easier than it sounds. After I labeled the connectors with masking tape
    (using the place they broke out of the harness as a guide) it took half a
    Saturday to replace the entire harness, and it took that long only because I
    work very slowly. The harness replaces all the wiring from the connector
    behind the battery to the connector by the A/C receiver/drier. I paid $300
    US for a new one, but somebody here will guide you to a source for a low
    miles used harness that won't crumble for about a third of that.
    The hoses that connect the turbo through the intercooler and to the throttle
    body are probably at the end of their life unless they have been replaced.
    Ditto the hoses that connect the Idle Air Control Valve (under the throttle
    body) to the throttle body. If any of the turbo hoses are squishy they
    should be replaced before they leave you cursing beside the road. The
    symptom of a hole in one of those is that the engine runs fine until it gets
    over about 2K rpm, then the turbo dumps air out the hole and makes the
    mixture to rich. The engine stumbles badly until the turbo spins down, then
    it's fine again. A full set of turbo hoses (less the turbo inlet hose) will
    set you back about $200 US from the dealer. The turbo inlet hose is
    different; it is as expensive as all the other hoses together and is not as
    critical.
    The voltage guage is part of the connectorized instrument panel. The easiest
    thing to do is pull the panel out and check out why the meter is doing
    nothing. It is trivial - IIRC it is nothing more than the two screws you can
    see from the driver's seat and unplugging the connectors when you get the
    panel out far enough.

    thanks mike....


    I gotta find out where to put my leads of the voltmenter to meter to
    check if the alternator is charging th ebattery.......

    I guess I could start with thte batt terms, but wehere on the
    aloternator do I check?

    it has a new wiring harness.....but it is a used one....hopefully it is
    not a bad used that is brittle vs a good used that has been
    updated.....

    how do I tell the difference?


    and , do the fuel injector wires run out of the engine harnes and into
    the fuel injectors?


    thanks

    Start with the battery. If you're getting proper voltage there,
    everything is OK.
    If you see lots of crumbling insulation or tape on the wires near the
    connectors, you have a problem.

    so,

    picked up the car...cahnged the battery....the PO didn't have water in
    the previous batt......




    no improvement...also the pos batt terminal was really hot.....so, must
    be a curretn draw, right?

    WENT thru all the fuses, and pulled out the ones that were not car
    engine keep running related.....

    pulled the sunroof fuse....no improvement....

    kept driving....



    then....all of a sudden, the volt meter started reading correctly..

    yahoo!

    don't knwo if it ws the sunroff fuse, gotta put in a new one....I
    dropped in down the console!


    but is works....

    now...I might get an adjustable regulator....any of you guys use those?
    the volts are at about 12V would like to see 14- 14.5V

    any thoughts>?

    but glad to have that taken care of....

    now, I have front brake problems,.....another story!
