220 volt outlet

Probably because it requires a different electrical current. Is your machine made to run on 220 volts? If so, it will not work on regular 110 volts (standard household current). You'll need to have a special line and outlet to power 220. The outlets are different because you really don't want to be plugging a 110v appliance into a 220v outlet, or vice versa.

no the dryer if it has an odd 3 prong plug is 220v and you need to place the dryer where you have access to 220 volts.

You do not want to convert anything to a 220 v connection !!!! Your RV is 12 volt DC and 120 volt AC.
Use a 30amp female to 15 amp male adapter to plug in to regular household receptacle on generator. Available at hardware store and RV stores.

I have never seen a 240-volt window A/C unit for the U.S. market. So, my guess is it's 120 volt.

The best way to verify this is to read the name-plate on the unit.

Another way is to look at the plug on the unit's cord. There are at least three types of plugs :: 120 volt, 15 amp; 120 volt 20 amp; and 220 volt. 120 volt 15-amp will fit a standard household wall outlet. The 120 volt 20 amp plug is similar to a 120 volt 15 amp, but will not plug inot a standard household outlet. The 220 volt plug is altoghether different.

Unfortunately, it will probably not heat up enough on 110 volts. You could change the male plug on the end of the cord to fit your 220 volt air conditioner or cloths dryer female plug.

Recommended spark plug is BPR5ES (NGK) W16EPR-U(Denso)
Spark plug gap is 0.7-0.8mm (.028-.031in.)

Air Gap for your ignition coil is .4+-,02 mm(0.016+-0.008in.)

most generators have a 220 volt plug on them from the factory, if it is a small one it might not have the capabilities of 220. If it has the 220 plug then you will just need to wire the proper 220 male end onto whatever you are trying to run.

Yes they should be able to help, but a welding supply shop might be a better idea, just make sure you take a picture or sample of your generator receptacle just in case for reference.

The battery '+' attaches directly to the starter and the '-' cable is grounded to the frame/block.

The Whirlpool Ultimate Care II cannot be outfitted for a standard 115 VAC wall outlet. Your dryer is a 220 VAC appliance. It needs to have it own dedicated 30 amp, 220 VAC circuit with the proper outlet and power cord installed. The dryer heating circuits and timer will not run on 115 VAC. I think you need to reconsider what you are about to do...
