Hi. Im trying to test 24v automotive relays..
I have picaxe 20m2 output to bcx 38. (not sure if symbol on drawing correct).
this then activates 24v coil on relay 1, 24v is then switched to activate 24v coil on the test relay.
each normal open/nomal closed then feeds 24v to relay S1 and S2 which switches a 3v input to picaxe 20m2
i have flyback diodes on each relay... is this correct or better way to do etc
relays S1 and S2 are used as im testing other switches and 24v sensors.
Ive not shown 3v for picaxe etc
is protection ok is circuit ok?
