trinity switch testing
Hi all.
Is there a way of testing the trinary switch.
My air conditioning chap is saying my system is over pressure.
New compressor fitted.
Condenser is off a working system.
Regased.
Tests from the plug end of the trinity switch all good.
Air conditioning worked for 3 days then just stopped.
Using the trinity switch plug compressor kicks in and engine fan working fine.
Thanks all
