    It works great except it stretches the aluminum too much.
    Still trying to figure where that .50 Cal round went that I used to punch the hole for the MNO mount went....

    We usually just stack a couple of old phone books on the roof before we shoot through it -- we get about 10-12 spanish phone books at work every year, so we have plenty to spare.

    That's the problem, I used only one LA Phone Book.
    Led is expensive, and I hate loosing that much led.

    "LED": What I did to my wife into the bedroom before we..... (WAY BACK WHEN)
    "LED": A semiconductor that lights up.
    "LEAD": What fishing sinkers are made of
    "LEAD": the wire coming out of Capacitors and Resistors
    "LEAD": the main role in a play or movie.

    The airbag circuit is the WORST POSSIBLE thing to tap from! The LAST thing you want to do is run the chance that, when you need it, it won't work.

    The fuse has already blown once. That's your warning.

    A real technician would know this.

    The fuse tap was put in backwards. Now the tap is on the LINE side of the fuse and the airbag fuse will not be endangered.

    Besides, what in the world did we do BEFORE airbags were invented? Oh, just DIED. My baby boy and his girl were SAVED by airbags when he went off the road coming down the Crest Highway (he was probably playing grab A$$ and missed the turn!). The car went off the cliff, and rolled many many times down a 100ft embankment. They WALKED AWAY from the crash thanks to the airbags!

    Also, that might make it go pop when not desired. Could break arms and necks.

    There this kind of Lead....
    What can I say, went to public school, not by choice.
    Looks like I need to dust........


    Besides;
    Where Pat tapped off for his extra juice is not problematic.

    Today I rewired the Orange box so that the battery Booster is ONLY engaged when I activate the Icom 706. Before it was permanently wired to the Gel Cel, which may have causes some drain. NOW, the relays place it in line when requested. However, the Gel Cel is ALWAYS being charged by the Engine voltage when the car is being driven. Hopefully that will give some better Gel Cel life.
