You have to run the amp gauge in line with the alt. You will have to remove the large hot wire from the alt and ether connect another longer wire to the end or move that wire inside the cab to the location of the Gauges. This wire will go to the + positive side of your new gauge. Then you will have to run another wire back to the post on the Alternator. These wires need to be large enough to handle the extra length and all the amps the alt. can put out max, say 120 amps at max. You will have to run about a #4 or #6 wire. Which is vary large, give or take, about like wiring in a 800 watt amp for sound. Please be careful, and disconnect the battery before messing with any wires, be sure of any radio or security codes you need once you reconnect the battery.

What gauge wire do ya use for an elec choke


A #10 wire and a 20 amp fuse should be good. On older fords, you can connect the choke to the stator terminal on the alternator (marked S or STA). On newer models, you need to use a relay. 25315497-dz1fkxf1fwolart5ai0divhk-3-0.jpg

1993 Lexus ES300 - Gauge cluster and climate control is not working - lights and dials are all non-functional (except clock and turn indicators). Alternator and battery check out fine. I replaced the 100...


IF a 10 amp blows you have a head short past the fuse . If it takes some time to blow the short may be at 9.5 amps on an intermittent basis or an occasion that the bare wire touches earth. Look at all the wires and harness and look for burn spots or places where the wires are pinched. Look for wire fault on the shifter area as it is most likely being pinched on the shifter movement.

How to hot wire fuel pump for 97


How to
Hot Wire Your Fuel Pump With a Relay in the Trunk




Terry Littleton - tlnfm@peganet.com


You Will Need

Get 15 ft 10 gauge wire, 3 ft 14 gauge wire, and a Bosch 4 or 5
prong 30 amp relay. Any place that installs car alarms should have a Bosch
relay. Get a heavy 10/12 gauge wire 30 amp fuse holder. They can be found at
auto parts stores and come in the old glass or new plastic spade type fuses.
Make sure it is heavy wire and not like most that use like 14/16 gauge wire. You
will need 2-10 gauge butt connectors, 1-10 to 16 gauge butt connector, 2-10
gauge female spade connectors, 2-14 gauge female spade connectors, 1-10 gauge
and 1-14 gauge ring connector. Soldering gun, wire
protector.

Procedure



  1. Disconnect battery. Put a ring connector on one end of the 10
    gauge fuse wire and attach that to the post at the rear of the alternator. Run
    it over to the front of the drivers side valve cover and attach to a piece of
    ten gauge wire that you will run to the back of the car. I put mine inside the
    car and it was actually easier.



  2. Run it through the hole next to the powermaster where all the
    wires go through the firewall. I routed it over behind the emer brake pedal,
    down behind that kick panel, took off the sill plate and put it inside the
    plastic wire protector (it does come open, just a pain to figure it out). Take
    out back seat and run it from sill up to opening that goes into the trunk. There
    are other wires that do the same thing, just follow them. Bring wire down to the
    hinge support. There is already a hole right there to put a bolt and nut through
    to mount the relay. I had a radioshack relay but it broke so I got a
    Bosch
    and it seems a lot sturdier. Good choice.

  3. Just a word of caution. Follow the wires down to the side of the
    trunk floor. The copper colored wire is the one to attach the trigger wire to.
    It looks like bare copper wire but is actually coated. The coating is so hard, a
    regular scotch lock wouldn\'t make contack on mine, so I cut out a half inch
    section of the insulation and soldered the trigger wire (a small piece of 14
    gauge from the relay prong 86) to there. I wrapped it in tape and put corrugated
    wire guard over it.



  4. The ground wire from the relay (a small piece of 14 gauge from
    prong 85) can go to the bolt hole you use to mount it to the hinge support. Just
    clean off the paint first. Then hook up the 10 gauge wire from the alternator to
    post 30 on the relay. The remaining prong on a 4 prong relay is the "Power Out"
    that will feed the alternator voltage to the pump(s). If you have a 5 prong
    relay the two remaining prongs should be labeled 87 and 87a. One is the "Power
    Out" when relay is energized, the other supplies power when the relay is not
    energized. Use a test light to determine.



  5. Run the remaining heavy gauge wire from the "Power Out" prong
    (when energized) from the relay through the rear of the trunk to the fuel pump.
    Notice the plastic cover over the BIG rubber grommet that takes all those other
    wires from the trunk out under the back of the car? Forget about getting your
    new ten gauge wire through there. Just drill a hole big enough to run the wire
    through covered with some corrugated protector. I put mine right next to the
    rubber plug. Then run the ten gauge wire to the pump.



  6. The 3 wires going to the sender/pump are Black-Ground,
    Pink-Fuel Level Sender, and Brown/White Stripe-Fuel Pump motor. Cut the
    Brown/White stripe wire after the connector on the fuel pump side and attach the
    new ten gauge wire. Leave enough to reconnect stock later if desired. Put a butt
    connector on the old cut wire so it doesn\'t short on anything. I wire tied stuff
    up neat and used wire protector. If you have an external pump, you can run
    another piece of 10 gauge to it for power from where it splices into the
    original pump wire.



  7. Now the wire coming through the firewall goes over behind the
    drivers valve cover and along the back edge of it under the EGR tubing in wire
    protector and splices into the other fuse wire from the
    alternator.



  8. When you turn on the ignition, you should hear the fuel pump
    prime. The only problem I had was in the connection of the trigger wire to that
    copper colored wire in the trunk like I mentioned above.

Hope this isn\'t confusing. I did it this way to keep things neat
in the engine compartment.

AMP GAUGE NOT WORKING BATTREY NOT CHARGING ALTANTIOR IS CHARGING


I'm assuming you had the alternator bench tested to know that it works.
On the truck the circuit from the gauge is what turns the alternator on.
You should have one large wire and one small with battery voltage, and the wire from the gauge is hot with the key on.
If one of the wires is not hot, you would need to check the circuit for a blown fuse or fuseable link.

Check the fuses there are 4 that you will need to inspect.In the engine juction fuse box its a 50 amp fuse (big ones).Then goe to the panel fuse box (under instrument panel) fuse 15 mini.Then inspect the battery connection this includes the alternator wire itself. If the fuses are good do a wiggle test on the wire and alternator remeber your alternator is internal vontage regulator equipt that means wiggle test the connections

93 model chevy 1500 5.0L 4x2 eating alternators. The alternator is overcharging. Someone in the past has done away with the fusible link from the alt. to the positive battery cable end and put in a circuit...


If the wires are overheating and someone put a rather large 50 amp breaker in the line, there might be wiring that is too thin between the alternator and the positive battery terminal.

I would probably replace the wiring with the proper gauge between these two entities.

When the wires get hot, it usually means they are not of the proper thickness or gauge all the way from point A to point B on a DC circuit.

It's like running too thin of an extension wire in an AC circuit.

Mercury sable 2001 auto. Can we use a 20 amp fuse to run a portable oxygen [breathing] machine for 5 hours.


Of course. You need to use the proper gauge of wire, of course.

If it were me, I would attach directly to the positive terminal of the alternator with an additional, new wire to run the O2 machine. I would run that to the fender, where I would mount the 20A fuse, then rune the fused wire to where ever this machine is.

Anything electrical you operate while the car is running is getting its power from the alternator. By adding your own wire to the (=) terminal, you make it so that the regular wire from the alternator is not being called on to run the O2 machine, plus the car. Of course, when the engine is not running fast enough to make the alternator provide the current for the O2 machine, the deficit in current will be supplied by power coming from the battery to the alternator through the original alternator wiring.

Need wiring diagram for 1967 camaro v8 changed from external regulator to alternator with internal regulator


I am assuming you are now using a 1976 style GM alt.
The most common and popular model.
You need one 10 gauge wire from the battery to the alternator output.
This can be run directly from the battery +.
Run a short 10 gauge wire from alt output to large wire at regulator plug on alt.
Run small wire on alt reg plug to Bat light wire.
A new alt regulator plug pigtail can be bought at any parts store and is recommended.

The existing regulator should have the connections marked.
One of those wires will be the bat light wire if needed.
If you have a amp meter or voltmeter in the vehicle.....use your existing large output wire (usually red) to hook up to the new alt output connection.
