Hi Hoop
Do you have an access code for your radio? Disconnecting the battery will un-power the radio so you might need to input the code to get it going again. But I am under the impression that most radios have never had the code used in the first place so then you won´t need it now.

Good luck

I just had the stereo replaced with a modern Alpine unit. I have asked the vendor to include the 3 Bosch relays in question. Hopefully this will fix the blower motor and A/C compessor.

And of course the irony in all of this... the blowers started working before I have even gotten to replace the fuse box!

 

I believe that generally the failure of RL6, RL7 and fuse box (melt) are symptoms of one or both blowers being worn out (weak?) and drawing too much amperage or normal-high amperage (HVAC calling for too much fan due to sensor faults) for too long.

I believe that the electrics really can't handle a normal full load (high fan) of the blowers for long. So, don't allow your fans to run on high for long or your solenoids and fuse box will fail.

Hi

The design is flawed and the tracks are not big enough to feed the required current, No ventilation in the box and the locating next to the engine does not help it much either. It is best to open the pcb and solder wires directly behind the tracks that supply the fans. The extra copper can reduce the load on the tracks.

Not using fans at high speed is no option here in the tropics.
