So if meade didn't protect a scope worth a couple of thousand buck from putting batteries in the wrong way maybe some other equipment is just as intolerant of too high voltage.
I don't know but JM2CW from someones who's only electrical experience is putting a screwdriver in a power point at 7 year old  |
An increase in voltage is a different matter to a small voltage increase.
Direct protection against reverse polarity must be provided on electronics to prevent an electronic BBQ where as a voltage increase in reasonable amounts won't even cause an increase in temprature of components. In fact a reduction in voltage which causes an increase in current is far more dangerous and is often refered to as browning out. The current increases to a point where heat is generated until insulation breakdown occurs and the result is another fryup.
