    MAD Bypass Alteration - Risk?

    Thank you for the info! In terms of the wire going into the interior, it is a larger gauge, so I think it should be plenty..? Really taking a less is more approach.. if that makes sense.

    Electrical Upgrade - Items to consider

    Currently it is a square back, 110amp, it just isn't cutting it. I can't run the car for extended periods without discharging the batteries, driving it at night it completely out of the question too.

    Risks of Running High Amp Alternator?

    Thanks everyone for the input. Sorry I should have mentioned this in my original post, I have already eliminated the Amp Meter and replaced it with an autometer voltage gauge. I have also bypassed the bulkhead connector completely. Would this just be a matter of upgrading this to accommodate...

    MSD Blaster 2 Coil Arcing

    I am really late in the game getting my car fired up before winter. Been a busy year! Anyways, I noticed that the MSD Blaster 2 coil was arcing off the orange wire. A bit of background, I switched my car over to Fitech FI last year and when doing so I removed and bypassed the voltage regulator...

    Proper Wire Size?

    All good points above! Last year i upgraded my alternator and upped the wiring and did the MAD bypass so i am confident that my electrical can handle it. I am also going to use a slightly larger wire for my main power to the unit to help reduce resistance and and kind of volt drop, but no...

    Proper Wire Size?

    I was hoping you would reply, you are always so helpful! Thank you. I found this: I read that Fitechs typically are about 15 amps, so based on this chart above, 14 should do the trick?

    Electric Fans always on because of Fan Controller?

    Hello, So I spent most of the weekend getting the car back together and got it running, something odd happened.. When I clicked the ignition on, my fans came on despite the fact that engine was cold (before I started it). First the controller was green, then switched to red, which is what...

    Fuse size to use

    Hello, I have upgraded my alternator to 80 amps and have run new wires into the interior and done the amp bypass, along with installing a volt meter. The new wires are 8 gauge to carry the heavier load from the alt etc. I am opting to go with a fuse vs the fusible link just to make it a bit...

    MAD Wiring with Autometer Voltmeter already installed

    Fantastic. I have it figured out now. Essentially when the VM was originally installed the amp bypass was already done. I just need to add in a larger gauge wire now. i am thinking that I will go with a fuse instead of the link. What size fuse do you think would be best? I am using 8 gauge wire...

    MAD Wiring with Autometer Voltmeter already installed

    Thanks for your input. Does this diagram make sense to what you are referring to? If so, what gauge wire do you feel is best to run from the alternator to the battery? Also, what fuse?
