    Total electrical blackout

    I ordered a 75A alternator, (thinking the original 60A was shot), no big draws in the system. It's my understanding from other posts that a faulty ammeter can be cause for the system to go dark, but maybe not associated with the charging circuit. I also have a new VR and starter relay on the...

    Can I take the A/C off?

    I always remove the ac from my old cars. Small blocks are easy just measure the length you need and bypass the ac. You will only be able to run one belt as the other would hit the water pump. Big blocks are more of a pain. I didnt feel like trying to find the non ac brackets for the alternator...

    Found this writeup on how to convert your Amp gauge to a Volt meter.

    Let me ask you this,if all the wires are new why would I want to bypass the alternator gauge? I dont drive the Bee at night.The reason I ask is Im going to switch out my cluster with a restored one in a couple weeks.

    Total electrical blackout

    For a 75 amp alternator, you would want an 8 gauge wire. That means the fuseable link needs to be a number 12. it’s always four wire sizes less than your wire size. you can send it to the starter relay or the battery, doesn’t matter. The battery wire is running there so either place is really...

    1967 GTX Larger Alternator

    I'd run a dedicated wire from alternator to battery in trunk. Run a fused wire from battery or alternator to your starter relay to supply operating power to the car/cabin. Or keep the stock charge wires in place and bypass ammeter as it will be ineffective with a wire direct to starter relay or...

    Voltage over 15 volts at all times. Stumped, see diagnostic list.

    Not seeing any posts addressing the voltage drop noted in the original post. You have a 1.3 volt voltage drop between the reference voltage lead at the regulator (blue wire) and the battery while under load? That needs to be corrected, take voltage drop measurements at all the connections...

    Ammeter to Voltmeter Conversion -- Existing Wire Question

    Another reason I prefer Tuff Stuff. Again, at the risk of repeating myself here, simple explanation, with no change to the bone stock loads, heathy stock charge wiring and related connections, the alternator will not create additional charge/load current. All things being equal, the car is not...

    Alternator to Voltage gauge

    I converted my Alt to a Volts gauge and was going to connect it to the back of the fuse box to a switched connection, since I don't have A/C and most likely won't use the heater. I have all new harnesses that I am ready to install. I am doing to connect the alternator gauge wires together, to...

    Overcharged?

    Bypass the Ammeter inside the car (which is a fire waiting to happen). This link will provide all the information you need; http://www.madelectrical.com/electricaltech/amp-gauges.shtml If you have a weak or dead battery, just recharge it completely (with a physical battery charger) rather than...

    Ammeter Bypass?

    Depends on how you did the bypass. If you followed madd which I'm not a fan of, then put a fuse/fusible link in that now attaches at the starter relay that feeds the cabin. If you left all the OEM wiring in place, place a fusible link in the charge wire from alt to starter relay. Sizing of...

    Total electrical blackout

    I have a 'square back' alternator, two field tabs, one of which I have grounded to the case. I've replaced the regulator and starter relay, tied the ammeter wires together and how have charging to the battery, 13.2 0 13/7V at idle. I will put a #12 fuesable link or two in the system, one from...

    Ammeter Bypass?

    Alternator output wire to Battery Positive or Starter relay should be sized according to the alternator rating and current demand. The fuse at the battery / starter relay should be a slow-blow fuse like a maxi-fuse or mega-fuse that is rated to protect the wire gauge size. The fuse is there to...

    Ammeter Bypass?

    Other steps? Should have been the first step, bypass the charge circuit bulkhead connectors, by far the weakest link in the original design. For those who have not yet mutilated their ammeter, check its connections, insulators, and then leave it alone. Learn to understand the information it...

    Ammeter to Voltmeter Conversion -- Existing Wire Question

    Thanks! I appreciate the reconfirmation! I think it's easy to get sucked in especially when the condition of reman alternators is such junk. In the past five years, I've taken back two to NAPA and one to RockAuto due to stripped pulley threads. Eventually I got a good one. But the...

    Found this writeup on how to convert your Amp gauge to a Volt meter.

    In a stock configuration, by-pass the charge circuit bulkhead terminals (the real weak link in the original design, always has been), check the connections/insulators at the ammeter then leave it alone. The ammeter will provide much more real time charging system status information than a...

    charging sys with electronic voltage reg.

    Many decades ago when I was a Chrysler Dealership mechanic in 1970, the electronic voltage reg. was on the 1970 cars. I remember grounding a wire on the voltage reg. wiring plug to bypass the reg. This would make the Alternator charge and meant that I had a bad reg. But being 5o years plus...

    Found this writeup on how to convert your Amp gauge to a Volt meter.

    This is not something you HAVE to do but just remember there is always a risk of melting the bulkhead connector somewhere in the future. So take it for what it is. The volt gauge modification would be perfect for this MAD modification if you bypass the amp gauge. You could then use a volt meter...

    Can i run 100% AVGAS 100LL?

    So one guy says run straight av gas No problem. Except you need an electric pump. another says any mix change requires a jet change Or it’ll run like crap. Others say use 25%-33% av gas no problem. the adjustment screws are for the idle feul mixture. wont do anything for cruising AF ratio...
