Cobbled up a timer circuit. More like finding it on Google.

Tester has 2 power supplies 5 VDC & 24 VDC. Circuit is set up for 5 VDC. My theory ends here. Was wondering if one of you IUEC trained wizards (Indirtwetrust) out there could change the values to work on 24 VDC. It would make the whole deal a lot easier.

Thanks
