ho is "they"?(quoted from post at 10:54:49 09/18/21) They gave me a full refund on the Ford voltage stabilizer. In the picture, you can see why it didn't work. 12 volts in 12 volts out.
aybe as sotxbill says, but I can't attest to points in that diagram. Have not seen that system before. What make & year model?(quoted from post at 15:38:05 09/18/21)
Jessie what's your take on this.
obo & I are very well aware of what an ICVR is......the discussion was about the series resistor being unusual and for myself, the crappy drawing of ICVR not looking normal.(quoted from post at 19:27:59 09/19/21)
when the points are close, the current flow through the heater wrapped around a bi-metalic spring... as it heats up, the bi-metallic expands at differnent rates, and starts to bend and thus opens the points by curling, which cuts off the current to the heater,,, which allows the bi-metallic metal to cool and return to its start position.. returning to its start position, the contact is made again to allow voltage to flow... and process starts all over... Exactly... the same as in a turn signal or flasher module. Except this one runs quite a bit faster iirc... also slang term is a voltage chopper as called in the 60s when used in the fast mode...also known as a mechanical vibrator used for stepup transformers by turning DC into square wave dc... The coils in the gauges (inductors) smooth the voltage back out to an average voltage... so if the chopper has a duty cycle of 50%on 50% off, and its fast enough.. you get an average of 6 volts minus vr drop due to current flow... A good rms meter will probably be more accurate. The schematic shows the fix heat coil to ground,, like a 3 prong flasher, meaning that the rate of operation does not change with load, where a 2 prong flasher has the heat strip in series with the load or light bulbs... this means a two prong flasher will flash correctly with there are exactly two bulbs in the circuit, and if one burns out it will change the timing of the flash rates.
