Subject: Re: LG 45 wiper motor amperage/wattage
Hi Bill, I understand how this works and it will not create heat in the same way that using a resistor would to control the speed of a DC motor but I would still be concerned about the motor getting hot. Unless the motor has been rewound the windings will be old and have poor insulation and whilst it may work ok as is slowing it down for an extended period would still tend to make it run hot.
The poor old wiper motor gets to work pretty hard for a small motor as it is...so not something I would do.
The type of wiper arms and blades fitted to the LG45 were common in their day and I suppose considered acceptable then but they don't ever work very well even when in perfect condition...
I have found that if you clean the windscreen thoroughly and then apply "RainX" the water forms large globules and just rolls off the windscreen giving better vision than the clanky old wipers. I have used RainX for upwards of 10 years on my motorcycle helmet, boat windscreen and old cars and it does do what they say on the tin...a simple solution to the problem allowing the wipers to be turned off most of the time!
Hope you are enjoying the Summer weather, cheers
