Hello all.,
Had no issue on assembly of kit, very familiar with soldering and electronic boards.
After assembly , during bench testing, the device worked beautifully for about 10-15 mins.
Then suddenly stopped working. No relays activate - only Red LED illuminates upon applying voltage.
No change when timer delay selector is rotated.
Any ideas ? Did the Timer IC go bad ?
Before powering for 1st time, all solder connections were double checked.
After failure, chk’d again, no indication of anything out of order or mis-installed.
Thanks !
