WHAT MAKES PURKEYS SOLAR CHARGE CONTROLLER UNIQUE

  Solar panels convert solar energy to electrical energy that can be used to keep the batteries on a vehicle charged. Solar charging systems produced by other companies are typically designed to charge batteries using a three-stage charging algorithm. The three stages of charging are bulk, top-off and maintain. Bulk – Consists of suppling a…

HOW TO USE A MULTIMETER: SOLENOID TESTING

Liftgate solenoids need to be tested under a load. According to Sales and Service Engineer Larry Rambeaux, “Use the ohm setting on a multimeter to determine if the switch is within spec for that particular piece of equipment”. To do this, switch the multimeter to “ohm’s” and touch the positive and negative meter leads to…
