LOWELL, Ark., Dec. 10, 2015 /PRNewswire/ -- Not checking for voltage drop can lessen a fleet's efficiency on the road. Purkeys engineers provide key tips on how to keep liftgates operating reliably.

When current has to travel a long distance on a vehicle, it is going to lose some of its strength along the way; this is called voltage drop. Excessive voltage drop leads to batteries continuously operating at a low state of charge. This leads to unreliable batteries, road calls, and shorter battery life.

Testing for voltage drop is essential for road time efficiency. All you need is an Autometer, or similar kind of electronic tester. Since it can be difficult to get the clamps in the proper place for testing, Purkeys makes adapters that make testing the system easier.

Purkeys engineers provide insight and demonstrational videos on how to test for voltage drop and more—all on their website.
