(Sarcastically speaking)......I plan on arc welding, using 3/16" diameter 6010-5P red wire, maybe 7018 LH or 7024 wire, using my 200 amp alternator, engine idling at 1200 rpm as the power source ....and a ground of course, should I bypass the bulkhead wiring and amp meter or just the amp...
If you want to run a 10 gauge wire to the battery or the post on the starter relay, you'd use a 14 gauge fusible link. The method I am aware of in selecting is whatever size wire you use, subtract 4. So, 12 gauge would be 16, 10 is 14, 8 would be 12 etc.
You will get many responses whether to...
If you believe the dual fusible link theory then the diagram Nacho posted supplying the high load fan direct off the upgraded alternator source is by far the better choice.
I'd still add an inline fuse for the fan circuit. The way your diagram is now; there is absolutely no protection...
About the Mad Electrical bypass? Just a few. Do a search on “ammeter”, plenty of past threads here on the subject, lots of opinions and some facts.
I’m running 130amp alternators, lots of added electrical loads (Including a Snipper/Hyperspark), correctly loaded on the alternator side of the...
Here is my take on this entire situation.....
Back when our classic vehicles were designed and built the current load on the electrical system was MUCH LESS than we have demanded with modern accessories and modifications.
Hence the reason to upgrade the circuit design. If you also bypass...
Does not matter if you run a one wire alternator or standard alternator the wiring stays the same. There is no ammeter. You bypass it. Dakota has a voltmeter.
Do you mean by-pass the ammeter? Did you read the Mad article carefully as to what vehicle type it was intended to address? You read all the ammeter/charging system threads here and concluded the Mad Electric approach is what everyone recommends?
Bypass the bulkhead connector charging system...
I disagree on the ammeter, my ammeter in my 70 is constructed exactly the same as my 75 truck, studs pushed thru a strap. That connection can get loose and cause heat, just reaching g up behind a dash with a wrench and tightening it is a bad idea, 2 wrenches so you do not stress the connection...
Battery is only 1-2 years old. I ran the sense wire to the starter relay main stud with a fusible link, which is also where the #8 alternator charge wire is. The MAD bypass deal.
Have you considered going to a Denso type alternator with internal regulation so you can bypass the firewall mounted regulator?
I made the switch from factory 1 wire alternator to the 60a Denso and it is perfect. Rock solid 14a at idle with lights and accessories on. Used the factory 69 BB...
I know this subject has been discussed endlessly, but this might be a bit different. I converted my 69 Dart over to a volt meter per Mopar Action (RE), and that works quite well. On my 69 RR I’d like to keep my amp meter which works fine. What if I bypass the bulkhead connection to and from the...
Its very easy to wire in your own relays. The headlamps do run thru the bulkhead and can have voltage drop. But lets back up a bit first. Measure the battery voltage at idle with the lights on. If it's low of fluctuating the relays will not help. If it's ok check the voltage at the headlamps...
First place I'd look is the bulkhead connector where the alternator wire passes thru, and see if its melted; next place to check is the ammeter. There is probably a poor or melted connection somewhere causing a voltage/amp drop.
With running accessories like the fuel injection, sound system...
I kinda have mine like that now. The exception is that the stock black and red wires are still connected to the ammeter. They still go through the bulkhead, but the OEM wire going from the starter relay to through the bulkhead is also a fusible link.
1. I understand that it's better to...
Well let's see...you have a 4 gauge from the alternator to battery, and a 10 gauge thru the bulkhead with a 16 gauge fusible link. It is always best to bypass the bulkhead, as far as hooking the 10 gauge at the alternator there is no need since you have the 4 gauge. If you had a 100% stock...
I had not. Do you have a link on Summit or somewhere else of the model you have? That would get rid of all the potential wire terminal connections and ignition switch path as well wouldn't it?
IMO....any additional accessory load(s) connected directly to the alternator's output connection must (or should be) protected with a fuse or fusable link. Since the alternator is also connected to the battery or charging system, a fault in the new connected accessory, without protection, will...
