wire over heating on self built generator, Help
Hi Guys, just built my own generator from very own design, its working great pulling about 2.25 liters per minute, i have used thicker plates 1 pos and 2 neg.
The only problem is on the car its pulling two much amps and the wire is heating up but the 25 amp fuse is fine, the 15 amp fuse failed after about 15 seconds, it works OK on the spare battery but when on the car it produces great gas, is there a way to reduce the amp power down with say a capacitor or some sort of amp adjustment ? I was told by a friend to put in a heavier wire but i don't want to damage anything so wont do that until I get some expert advise.
This forum was recommended to me, thanks in advance, if it works perfect, I'm happy to give you the formula. PS its the pos that over heating.

Get a turkey baster and suck out some of your electrolyte and refill with water. That will reduce your current. While you're at it, put the 15 amp fuse back in until you find out what the safe current is for your wire size.

Too much current on wires that are too small by a flammable hho generator is asking for an accident.

For 25 amps, you need 10 gauge wire, minimum.

Get yourself the My new current sensing PWM:
It is better not to reduce the electrolyte. It is better to work out what the ideal current is then put enough electrolyte in so that it uses that amperage when it is cold. Then adjust the PMW so that is the most current you can draw.

As a cell warms up iy will use more and more current and produce more gas in order to havce a constant supply of hydrogen it is better to use the PMW as I explained.

What are you calling hot? 100 deg? 150+? can you touch it for more than 5 seconds?
