I'm having trouble wiring my hho cell to the vehicle. I've wired 10 gage from the battery to the 30mA 4 post relay. The relay is activated by the vehicles fuel pump wire which is considerable small gage. Then from the relay to a 30 amp type 2 circuit breaker. From there it goes to the cell positive on the positive and negitive to negitive. The problem I'm having is the cell only needs about 4 volts to work properly but is receiving 14v from the battery/altinator causing the cell to heat up and melt. If I put a nother cell in line the cells stay cool but the relay melts and the wire to the battery is extremely hot. Does anyone have some ideas on how to reduce the voltage to the cells without melting the relays? Basically I have run out of ideas and need some help. I look forward from hearing from everyone.
