Question about 1993 Mercury Cougar

1 Answer

1993 Cougar Specs

Hi:

I would like to put on a hydrogen electrolyzer in the vehicle. It draws 20-32A of current @ 12V. What is either the rated current output of the factory alternator?? I looked in the haynes manual but they don't have specs. I will take rated power output of the factory alternator since the current would be easy to calculate. I also need to find out the maximum electrical load of the vehicle so I can figure out if there is room for 32A or (384 W) in the system. If the load is too great then we will put a bigger alternator in for this. Furthermore we will be removing the A/C system (with the help of a licensed mechanic for the freon drain). So if I can get help figuring out the draw of the A/C system for my calculations that would be much appreciated.

We will look at the battery to make sure that it is okay for this.

I know I am asking alot and please only reply with rated alternator output, the appropriately sized new one if needed and maximum electrical load of the vehicle and current draw of the A/C system

    the rated ouput of the alt is stamped on the case, it varies from vehicle to vehicle according to what engine, and accessories installed like AC and other electrical draws. I can tell u right now u are going to have to install a bigger capacity alt.

I made an electrolizer my Corolla and a smaller unit for my 150cc scooter. I got tons of bubbles so I expected stunning fuel consumption. In the end I chucked them out because they made no difference either to the power or the consumption. Remember, your alternator will be working flat out all the time to keep up with the energy needs and this alone will affect your consumption. Secondly, your engine management system will notice that your car is running leaner and will richen the mixture to compensate. More fuel consumption. You might find that you will put a lot of effort in for little or no return. The only solution for high fuel consumption, apart from a properly tuned car, is a lighter foot.

What is the current draw on a sigma 25 five speed 12v trooling motor.


the current draw will depend on the load on the motor so low gear (1st) will be a lot less that high speed (5th gear)
however on a 500 cc amp battery, with trolling it shpuld be around 5 amps

As soon as I turn headlights on it blows the fuse for gages on dash no wires touching and lights don't come on gages work if I don't turn headlights on


Hi Bobbi
A 50w Headlamp will draw 4 Amps (Ohms Law 50/12=4.1)
So... 2 Low beams will draw 8 Amps.
Obviously more for high beam and high wattage Quartz Bulbs.
That is a lot for a small switch (contacts) to handle.
This is why a lot of vehicles use a Relay to power the Headlamps.
The relay is connected directly from the Battery to the Headlamps.
The large internal contacts can handle the higher current (30A) and the dash headlight switch connects to the magnetic coil inside the relay and is only used to pull the contacts closed.
Does your circuit include a relay.? Do you hear a relay click?
simple headlight relay wiring

To assist with your troubleshooting, try disconnecting one head lamp bulb to reduce current load. Does the fuse blow?
A temporary12v circuit breaker could be substituted for the fuse until you determine the problem.


If the circuit is using a relay then there will be a fat wire going from the battery to the Relay. The fine wire on the relay input is the trigger. A 12v test lamp is really useful for troubleshooting around the car. Also a cheap multimeter. Clamp style current meter is also handy to see exactly what current is blowing the fuse

There is a 10A circuit breaker also like above

Im having a problem not getting enough voltage running through the truck put a brand new alternator on and when my truck attles my headlights go dim nd it shuts off


Have a load test done on the battery to check for cell failure as the alternator may be putting all the current into a shorting battery. Check the output of the alternator as the regulator may be faulty. Alternators produce 14.5 volts at 2000 rpm and the current is set according to requirement. That is with 14.5 volts and full current draw the alternator is capable of producing the rated amps ( up to 120 amps) If you have extra power requirements ( driving lights --massive amplifier) the total current draw may be more than the rated amp of the alternator and so the battery will eventually run down and there will be insufficient power to run the ECM and it will stop.

How to make 12v DC power supply to power my winch


use a 12v car battery and a small battery charger... a winch draws alot of amps when in use... so you need the battery to supply the amperage ... 12v power supplies are low amperage output supplies... so will not work (inexpensively).

Hi,
if there is no power coming out from the relay, that will be the problem. as you said it is new,check it manually by connecting the terminal into the power source and check the continuity of the the output from the source.
Sometimes there is new parts that has a manufacturer defect. try another relay.

Hope that helps you out!

Hi,
The size of the wire going from the + side of your battery will influence the amount of amps available to the generator.
Amount of amperage produced by the alternator is affected by engine RPM. The regulator senses battery condition and battery draw and controls charging up to the rated amps on the alternator.
The peak amount of charge the alternator can deliver will be at be off idle and up till the regulator senses max out put of alternator then holds it there.
You should be able to draw all 35 amps from a good battery with the right size wires with the vehicle off.
Some generators use Pulse width Modulators to help control the amps.
I am no expert on Hydrogen Generators so you are way ahead of the game than me. I do keep my ears to the tracks on them.
My best wishes to you on your adventure.

Put the Original Tail Lights back in the Vehicle. Unless you are a qualified Electrical or Electronic Engineer that can calculate the required resistance that must be added to the circuit to bring the Current back up to what the Light Bulbs draw, you are not going to get it to work properly. The LED lights probably draw about 1/10 the current that the Light Bulbs draw or less. This is why the Flash Rate is so high. You will have to Measure the Current for Both the Bulbs and the LED's then determine what parallel resistance is required to come very close to the Bulbs current. Probably somewhere close to within 10ma of what the Bulbs draw. If you have a VOM meter you can measure the current. A Resistor would have to be added in Parallel with the LED's of sufficient wattage rating to bring the Current Back up to what the Bulbs draw.

Ohms Law E=IR
E=Voltage
I=Current
R=Resistance

To solve for I divide E/R
To Solve for R divide E/I

Good luck!

I would like to know the voltage and current needed to drive the driver and passenger seat adjustment motors for a 740i BMW (1999)


Assuming the vehicle is 12v, then it would need 12v and between 6 to 10amps with nobody on it.
I know this because I was a seating designer and often had to power the seats, best way would be to use a car battery, don't use an adaptor it will not be strong enough.
It would draw more power with someone on it.

Charokee charging problem


I'm not sure whether the high or low side of the field is controlled; typically, it is the low side with 12V applied to the field and the low side controlled by a a transistor in the ECU. If you are measuring 12V at a field terminal, it may be normal and when I have monitored this voltage on the controlled side, it was always lower than 12. I can't give you a range because ot the variation of load on the output.
If you measure the resistance of the field winding, you can get a rough idea of the current it draws. For example; measuring 100ω would yield a max current of ~120mA. ( I=E/R)
I have something in mind about 200ω but that seems too high but it should be in the range of ~100 - 200ω.
