How can i run my coleman hwod unit from 12v car battery instead of 6v coleman battery

It's pretty simple, if you have 2 6v batteries and you have a 6v motor if you hook them up in parallel it will make the batteries last longer, but if you hook them up in series it will make the two 6v batteries = 12v. Too hook them up in series you will just run the + to + and - to -. If you hook them up in series you will have your negative cable on the - of one battery and the + of that same battery hooked to the - of battery #2 and then the + of battery #2 to the + cable. And it is the same with different batteries. Two 12v in parallel is 12v but two 12v in series is 24v.

Hi Ebrahim
Defiantly not you cannot use a 12v supply on a 6v battery in the worse scenario you could blow up the battery by putting to much voltage into it, you will need to find a 6v charger hope this helps

If under warranty have it repaired/replaced. If not under warranty then some basic troubleshooting. Most likely a battery issue howerver;


To test the fencer output you can power the fencer from either a standard 6V lantern battery (6V fencer) or a standard 12V automobile battery (12V fencer). You need to rig wiring observing polarity.


To test battery, remove and check voltage with digital volt meter.
A fully charged 6V SLA battery should read 6.2V minimum and a 12V should read 12.4V minimum. If a 6V battery measures 4 volts or less then battery has likely failed. Likewise if a 12V battery measures 10 volts or less it has likely failed. Before replacing a suspect failed battery, connect the battery to any standard 6V/12V automobile charger and see if it will take a charge. After the charging period;

• If battery takes a charge, reinstall back in fencer and see if fencer output is hot. If fencer fails output, repair/replace fencer. Else verify the fencer is charging the battery. While battery is installed in fencer measure battery voltage with a digital volt meter. Typical minimum voltage is 13.5V for 12V and 6.7V for 6V. If fencer fails to meet minimum battery charging voltage, likely the fencer solar charging system has failed, repair/replace.

• If battery fails to charge, likely battery is end of life. However fencer could still not work. Test fencer with alternate power source (see previous tests). If fencer ok, replace battery.

There should be a small white ceramic block on the firewall - this component cuts the battery voltage from 12 to 9 volts for the coil and ignition system. It has 4 wires and is called a ballast resistor.
You may need a book with the wiring diagram to be able to test it. You should have battery voltage going in and something like 9 volts coming out.
You can also run a wire with a fuse from the battery to the positive side of the coil to check the system. Disconnect the factory wire from the coil first.

Main functions:
(1) The HB-1206S battery charger has the features of convenient operations, reliable safety and high performance.
(2) During charging, if turn up overload, the battery charger will keep itself at normal current and normal voltage with its self-automatic protecting function.
(3) If being short circuit, the battery charger will switch off itself, and turn normal after one or two minutes.
(4) The output current of the battery charger is very stationary, so it can protect the battery charger very well. It only costs 3 or 4 hours to fully charge the batteries.
(5) Indication of charging: the battery charger has 6 pilot lamps. The more pilot lamps shining, the less electric quantity is. The charging process finishes when all the pilot lamps go out.
(6) The battery charger can be switched between 6V and 12V, so it can charge for 6V and 12V accumulators. You can select 6V or 12V according to your own needs.
(7)The operations are very convenient: Put the red clip to the positive pole of the accumulator which indicated "+", and put the black clip to the negative pole of the accumulator which indicated "-", then plug in power source, the accumulator will be charged.

6V boat?
Then you'll burned everything...
12V boat? Put a 12V battery in it instead of a 6V. should work.

Look at battery is it 12v or 6v.Most likly it is 12v.

check to see if 12v at alt power terminal then unplug three wire connector with key on should have 12v at green wire with red stripe 12v at black with orange (could also be grey with yellow)may be a white with black wire with 6v when running plugged in
