Havis Charge Guard Issues

[KC4YIN]

I have a Charge Guard in my truck configured for DC mode and 30 minute power off delay.
I have recently been experiencing parasitic battery drains after the truck sits for 3 to 4 or more days.
Just curious to know if its possible for the Charge Guard to fail in such a way as to cause a parasitic drain.
The Charge guard does function normally as far as start delay and power off delay is concerned.
Thanks.

I had the same problem on my Toyota Sequoia. Nothing worked until I changed it from DC to IGN

How is it wired?

Are you feeding the main power for the radio through the Charge Guard, or just using it to power an ignition sense on the radio?

I agree with Toby, if you are relying on the DC voltage to trigger, it's always going to be drawing something. I use Lind timers and always wire them to an ignition trigger circuits. Never had an issue, even when wiring radios direct to battery power and only using the radio ignition sense to the timer.

I did not have ignition sense anywhere near the rear of my vehicles where my ChargeGuard and radios are mounted. (The only fuse block with ignition power is in the engine compartment). I switched it to "AC". which means it detects the slight AC ripple/voltage change when the alternator is running. When I start the car, evereything fires up, and when the engine shuts off, the timer starts. Perhaps they have changed circuitry recently, but my ChargeGuard has a hard shutoff at 11.0 VDC if the battery gets too weak.

What's the main radio and is it wired directly to the battery?

We had an issue where vehicles were coming up with drained batteries after about the same amount of time (shut the car off Friday afternoon, and by Monday morning it was dead); turns out the cameras and stuff were wired through the Charge Guard, but the main part of the radio (APX6500) was wired direct to the battery. Even powered down (ignition sense or button push), the radio still drew just over 2 amps. Drained the battery neat as you please.

We ended up having to put a battery cutoff switch in the line between the battery and the radio; cleared it right up as long as the vehicle user remembered to shut off the switch.

In later installs they wired a relay with high-current contacts into the Charge Guard to automatically switch off the main radio when the Charge Guard shut everything else down.
