Anytime backup troubleshooting

Ok, then the relay is NOT doing the change over. Green wire is not providing power to relay, or relay is AFU or ground is not good (relay)

 

My first assumption is also the relay as I’ve taken the time to carefully solder all connections etc. I’ve tied both grounds together (also soldered) and grounded to head unit. I’m still waiting for anytimecamera support to get back to me, hopefully it’s just a relay swap and not the relay harness as well.

 

Do you have a DMM? Verify continuity and relay function. Also the juice from the added harness.

 

I do, can I verify this at the switch side? I may not have access to the relay/harness (at least with a DMM) due to being tucked away.

 

Switch, yes.

 

nice. I’ll admit it’s a tad out of my schematic know how, do you know which pins to verify as I try to toggle back and forth?

 

First verify there's juice.
Switch connector pin #4 _DMM (+) to Ground Switch selected to Front camera.

 

the switch camera icon itself illuminates, not sure if this is a telling indicator of power.

 

No, switch illumination is not part of actuation.

Verify switch connector is as my drawing. It might have changed a bit.

 

I think I get it. So pin 4 to GND should read x when toggled to Front, while pin 5 to GND should also read x when toggled to Rear. If rear does not, then this confirms relay inactivity?

BTW - I appreciate the continued help

 

Green (4) is only input to relay for video source change...

 

lol will try tomorrow. Wasn’t home all day but stay tuned and appreciate the help.

 

so I am getting ~15VDC when measuring positive probe to green (pin 4) and negative probe to GND (pin 1) when camera is toggled to front cam. When cam is toggled to rear cam I get 0V.

 

The there's a fail towards relay, relay itself, or relay ground. Must access the relay to verify.

 

any suggestions what exactly to prob on the relay harness? I can possibly get access, I think.

 

Green wire going into relay to ground, then test relay ground.

 

P.S. You can remove the relay from the base and test the pins, then test the relay away from the base.

 

ok measured via pins in back of relay harness and confirmed GND is good and green pin to GND is reading ~15VDC in front cam setting and still 0 when toggled to rear.

 

Bad relay, remove it. Test it away from base.
