low relay resistance coil

Another FIGJAM Howard? (I was expecting a WOMBAT or WOFTAM.) Yet another example of a solution without the problem or situation being fully understood - or at all. (I should have said "repair"; those solutions are done all the time by management, and some Florida audio forums.) So it is some system that senses load (coil) current, or feeds thru the coil, or is still totally misunderstood. I'll bet it's a hot little resistor though....

Thank Old park. That was grate you solved my problem I put the resister across the relay coil and that was it.

Since I don't know maybe Oldspark or some other erudite chappie could explain the pros and cons of placing a resistor across the coil.

Old spark. The resister value you give me for the relay. Just what I wanted you are so correct.I like to have other choices with my project what value of transistor can I used

It's like I alluded to in my 2nd reply... "If the relay's coil load has to be something specific... - somewhat like an alarm loop circuit. It checks it isn't a short nor open, else checks for a specific impedance (which is only provided by their special Part No which is a rehoused $3 relay and $2 resistor selling for over $123), else has a recalcitrant impedance dependent driver.... However the OP's system is such a puzzle, any reality is likely. And using a transistor? For what or why???

Thanks, Peter.
