I have a cyrix ct-120, I think it works perfectly. I specify that I have checked all the connections, that I have done the tests that you recommend.
When I disconnect my starter battery from terminal 87 of the cyrix, I have a voltage of 13.1V. When I reconnect the starter battery, the voltage drops from 13.V to 12.4V.
So I have questions.
Is it normal that the voltage drops immediately after everything I connect terminal 87 while the cyrix has not closed?
Is it normal that when I turn on my engine and the alternator does indeed supply 14.8V, the voltage on terminal 87 remains around 14.6V?
Or quite simply a defective mass in the installation can it cause these voltage measurements which seem abnormal to me? I specify that I have checked that terminal 86 on cyrix was on the general mass of the installation
Best regards
