Why is my battery isolator not working?

Why is my battery isolator not working?

Check the voltage at your batteries. If you are not seeing close to the same voltage at the battery as at the isolator (minus some small voltage drop over the wire), you have another problem. If the voltage is 12.7 volts or below, you are probably only seeing the battery voltage and no charging at all is occurring.

What does red light on REDARC mean?

To summarize this – the main things that are seen are either a poor connection to the earth return in the trailer plug or Anderson connections OR an under-rated cable on either the vehicle or van/trailer side.

How do you test a Redarc dual battery system?

Steps

  1. Leave input (VIOLET) wire and earth (GREEN) wire connected.
  2. Disconnect output (BROWN) wire from battery. (Do not allow BROWN wire to contact chassis/earth).
  3. Connect 5W test lamp between BROWN wire and vehicle chassis/earth.
  4. Measure voltage on the input (VIOLET) wire 24V connection.

Why is my Redarc flashing green and blue?

The green/blue flashing LED that is on displayed on the remote head indicates active calibration has not been completed.

Why is Redarc blinking purple?

The 1 yellow/3 purple flash sequence is normally caused by an intermittent connection through the trailer plug. The most common fix is a spray of WD40 Etc into the trailer plug or socket. While the plug is out, check for any crushed pins making poor contact.

How do I know if Redarc is working?

Once the remote head is GREEN, have someone watch the test light. With your foot on the brake pedal, as you slowly increase the dial from 0 through to 10 you will see the test light go from no brilliance to full brilliance. This is normal operation.

Why does my red arc flash blue and green?

This is normal and the unit is in sleep mode. Breathing, as opposed to flashing, is the LED gradually getting brighter until its brightest point and then gradually dimming off. Whilst driving with the trailer connected, the LED indicator will flash blue and green. The Tow-Pro™ Elite will calibrate as you brake.

Do I need a battery isolator with a DCDC charger?

We recommend DC to DC chargers over isolators because they protect the vehicle’s alternator, and maximize the battery’s lifespan. DC to DC chargers provide a multi-stage charge to the house battery and push more charge current than an isolator.
