    I have a 1999 360 Modena. The battery went dead and I tried to jump it, unsuccessfully, with a portable battery pack. Being unable to disable the alarm system, I discovered that the alarm system fuse (5amp/ # 74) was blown. After replacing it I found that every time I turn the battery knob back on the fuse will blow. I've tried disconnecting the siren as suggested by a previous post with the same result, the fuse blows as soon as I turn turn the power back on. Does anyone have any suggestions before I resort to having it hauled to the dealer?

    Thanks.

    A lock mechanism can be failing which causes the short. Identify each part of the car that locks and leave them open one at a time to verify which one is trigerring a short in the system.

    Locks I can remember are below.
    Driver and passenger door
    Frunk or front trunk
    Engine trunk
    Gas door

    Goodluck.

    Yep, the above makes sense.
    Other options, less likely, are a short in the wires if when you tried to jump it you melted any or the alarm ECU (all very unlikely)

    just to close out this topic in case anyone has a similar problem...it turned out to be the anti tilt module that got cooked...

    And maybe a mention that jumping a battery can be disastrous. To be honest, I've heard that jumping is bad but never saw a first hand report This is proof in the pudding
