    You should look for heat shields
    If the previous owner was serious they would onstall these.
    Keeps the alternator temps down
    Also theres one for the ac unit
    I th8nk they are only a few hundred bucks

    Well good news and bad news. He did install the heat shields but he also disconnected power from the cigarette lighter and routed it to an auxiliary USB port. I guess I could still get the voltage reading from that but I'm not sure how to without taking the panel off and just using a voltmeter.

    Do you know where your rear battery terminal board (box) is in the engine bay? i.e. under the right hand side cover. The terminal board is marked with a red "+". You'll need a 3.5mm (?) allen key, if I remember correctly. If you don't have any tools other than a voltmeter, you could pull out one of the fuses in your luggage compartment and check the battery voltage going to one of those (e.g. Fuse 1, 2, 3 or 5). i.e. headlight motor and hazard light fuses.

    Straight volts, however, is not going to tell you everything you need to know about your battery. Real battery testers are a little more expensive.

    Actually, you may not even have to pull the fuse. Many fuses have small holes in the top of them into which you can insert a voltmeter probe. Just find a local earth to complete the voltmeter circuit. There is a big earth forward of the luggage compartment relay panel.

    Checked the voltage through the fuse and everything seems fine. It increases when revs go up but not more than is in the normal range so the alternator is working fine as well. Also drove the car for about an hour today and everything performed perfectly .I must say, what a truly awesome experience. The sound that that engine produces is just marvelous.

    Just re connect the cig lighter should be no big deal, could just be a fuse because I. Do not know why they would disconnect when they could just tie in in parallel. Either way should be an easy reconnect.
