IT CONSISTS OF TWO DIODES WHICH BOTH TEST GOOD (REVERSING OHM METER LEADS GIVES VERY DIFFERENT READINGS) ONE FEEDS THE MOTOR BATTERY THE OTHER THE HOUSE BATS. & V. REG. FEEDS THEM BOTH. THE MOTOR WAS ADVERTISED AS PUTTING OUT A...

MERC - V. REG. OUTPUT

THE V. REG. OUTPUT IS 5 V from my MERC 40 HP outboard. I was expecting 14-16 V. WHY SO LOW?
THE INPUT TO my BATTERY ISOLATOR IS 5 V. THE
OUTPUT IS 13.6 V TO EACH BATTERY. HOW DOES THE VOLTAGE INCREASE ? WHAT HAPPENED TO THE 0.7 V DROP?

PULSE HELP!

A RELAY NEEDS TO BE ACTIVATED THEN DEACTIVATED FOR 1-2 SEC. THEN ACTIVATED & REMAIN ACTIVATED. THE PULSE CANNOT BE INITIATED BY A MECHANICAL SW (relay is part of an alarm system). A DPDT SW ON THE RELAY IS AVAILABLE AS A PART OF THE PULSING CIRCUIT. IDEALLY THE POWER FOR THE PULSE CIRCUIT WOULD COME...

MOMENTARY SW

HOW DOES ONE ELECTRONICALLY MAKE A MOMENTARY SW? IN THIS CASE IT MUST BE ACTIVATED WHEN A RELAY SW CLOSES & REMAINS CLOSED. (12 V.)
