Re: Bosch 24 v coil and other bits wanted
They are a decent company & have interesting stock. The things may appear similar & have identical readings of resistance but one might be for a positive earth & the other for negative?
The other thing to consider are these actually 24v coils or are they coils designed for use in a 24-volt system in which case they may be 12v coil that work with a ballast resistor? If so it leaves the field for alternatives a bit wider.
The way to find out is to measure the voltage that feeds the cable to the coil & it should read 24 volts. Then close the CB points & if it is still 24v then it is a 24-volt coil, if it drops to 12v or so you have a ballast resistor in there somewhere.
