Im having trouble nutting out a coil tester, below is the schematic I was following its one put together some time ago by another member.
Ive tried some dry test runs without success.
My shopping list was as follows C2 .22uf 275vac40/100/21, the relay is a D12Volt DPDT 10A/24vdc/220VAC, the D1 diode was a 1N4007, the C1 cap is one from the type of ignition systems Im going to test the coils from. The R1 resistor is a 10W10ohms. Power supply is from a 12volt battery.
If I try testing the circuit and runnig the + through the C2 resistor.... no joy, if I bypass the C2 the the relay buzzes furiously. Which I believe is not so good. Am I using the wrong resister in the C2 position.
I will be testing a lot of coils and dont want to be burning out relays frequently.
I'll be testing old magneto coils with this unit if I ever get it running and yes I am a novice so please be gentle.
