If you want to keep the ammeter working as factory I would do 3 things. Bypass bulkhead connectors for alternator and battery feed. Check the ammeter connections to make sure they are clean and tight. Use larger wire than stock.
Hey Guys I Got The Ammeter Bypass Conversion Done On My 1969 Roadrunner.
I Sent It To Classic Instruments And They Converted The Ammeter To a Voltmeter
I Tied The Red and Black Original Ammeter Wires Together.
What Other Steps Did I Need To Take For The Rest Of The Wiring In The Engine Bay...
This is the age-old debate about ammeter bypass.
Many people don't like the idea of all the charging current going through the bulkhead connector (twice) and the ammeter. Many other people will tell you that it's fine so long as you have clean contacts. A modern alternator can easily triple...
That is WAY over my head. I know almost nothing about wiring. I did install some type of "ammeter bypass" a few years ago so power doesn't go through the amp meter (I think that's what I did) and it goes through a really big fuse instead (100A I think?). It is a 1970 plymouth road runner with...
Doesn’t need to go with painless wiring or any other either. EVEN LESS ABOUT MAD wiring mod Just read about firewall path, parallel wiring, bulkhead bypass ( which is NOT the ammeter bypass ), fleet alternator wiring Bypass… any of those keywords will take you to the solution.
Learn first...
Gray box is your voltage regulator. It could be relocated or if you use an alternator with internal regulator the OEM one can be eliminated. The rusty box looks similar to the seatbelt interlock bypass switch but it looks different from the one in my '74 SE. If it is indeed the bypass and you...
You have a fuse link. When you overload that the whole system is most likely dead. There are some variants depending on year. You take a older car and load off the alternator stud you are asking for problems. Worse when the alternator dies and all loads are on that old wiring. Failures will be...
Yes bypass the ammeter AND bulkhead connector for the feed into the cabin.
Yes I read the MAD article.
I read several threads on this topic but not all lol.
I currently have a functional wiring harness and bulkhead connector. I even use deoxit on the connector.
I just want a safe and...
Maybe you need to summon @Nacho-RT74 to weigh in.
Since this is always a lively debate..... :popcorn:
I also installed a nice new 95A alternator, but I still have 50yo wiring, so I have done the ammeter/bulkhead/underhood bypass' and run a voltmeter.
I’ve went completely over this thread again, learn something new everyday and ate some crow along the way. Some things have changed like the likes of led lights. With the led lights you no longer need to do the famous headlight relay upgrade. My LEDs on dim only pull a tad over 3 amps and with...
Are you running a high amp alternator w a lot of draw on it, stereo amps, fuel injection/electric fuel pumps, dual electric fans etc...? If not, no need to bypass ammeter. I did a full conversion so it's the same gauge, but the guts are a voltage meter. I have 120 amp alternator and a lot of...
The referenced difference in construction is exactly the plastic cluster frame of the trucks and the pot metal cluster frames of the passenger cars, as referenced in the Mad Electrical article. The plastic being much less tolerant of any heat generated by resistance at the stud head to ammeter...
I am thinking that fuse link was on its way out already and it was just time. The starter positive wire being off should have done nothing. The fuse link should never be larger with stock cab wiring. Maybe you have the stock black wire hooked up at the alternator, along with your bypass wire and...
The ammeter lovers will be in to tell you that you are incompetent and know nothing in a few minutes. :lol:
I don't like the mad approach, however, IMO, the bulkhead should be taxed to provide power for loads requested by the cabin. The packard terminals in reality were not dsesigned to carry...
That would be considered a modified Chrysler charging system, then power connections can be made most anywhere between the battery and the alternator without the risk of overloading original connections/wiring, you lose the function of the ammeter however and the information it would provide...
I’m building a 1967 GTX for a customer and have a couple questions regarding the charging system.
The car is a 1967 GTX, it’s a 440 non a/c car that is getting a Procharger and a FiTech fuel injection. We’ve relocated the battery to the trunk and have run 4 gauge wire from the battery to the...
I don't care what cars today have. Does our 60s car have the same electronics as a 2019 dodge pick up? NO so don't compare .
So as you stated the only fuse , is the fuseable link on the engine side of bulkhead.
You fry your fuseable link, the system is not dead, until you turn off your car...
