hello peeps! plano ko po mag-install ng isa pang aux fan for my condenser. malamig naman ang a/c ng auto ko pero pag tipong tirik ang araw tapos traffic e it gets a bit uncomfortable. i'm planning to do a diy, pero i'm unsure kung pwede ako magtap ng kuryente dun sa relay nung existing na aux fan. can i do this or should i be installing a new relay as well? plan ko din is manual switch lang yung 2nd aux fan.
You can install 1 10-12 inch fan to cool it down on traffic. You also need a separate Heavy Duty relay so you will have enough current to run it more sufficient. do NOT tap the Power wire to the A/C relay. Run it as a different system so when its cold already you can shut it off and less drain for you battery and less load for your alternator.
Using the same relay would add up more load to it, thus hihina performance ng orig Aux Fan, and this would be another problem to you since. Better install a new relay or circuit for that matter para mas safe.
be sure lang na yung pin 86 ng relay ay sa ignition on (or run) lang nakatap para kahit malimutan mo naka on ang switch ng fan ay hindi madischarge ang batterry mo
