Hi All,
I have a issue I am trying to resolve. I am using a timed output relay (Redarc TIM05) as a kill switch. Once a momentary button is pushed, an output is set at 30 seconds, supplying 12v to pin 86 of a 30amp relay that runs inline with the starter motor trigger. The issue I am having, is that this timed relay seems to be very sensitive to input voltage, which it requires to be present at all times whilst the timed output occurs. When the starter motor engages, the voltage at the battery drops from 12.8v to 11.3v, causing the timed relay to shut off its output.
My question is, would a capacitor be viable to smooth the voltage dops out whilst the vehicle is cranking? If so, what would be the best way to implement?
Cheers
EDIT:
Worth a mention, this is a 1960s Chev, which I have done a full ground up rewire. The customers intentions were to have a secondary start inhibit that’s not obvious to an unfamiliar user. This isn’t meant to be killing a running engine. A momentary switch with a timed output was chosen for the ease of use whilst keeping the switch hidden, so not to disrupt the immaculate fit out of the interior.
