Check for continuity between terminals "R" And "L", as well as the presence of conductivity between the terminals "Y" And "R".
Colors: L - blue, Y - yellow, R - red
2. Test in ON position, connect "+" battery to the output "+V", and the battery to the output "Ls". Then check for continuity between the terminals "R" And "L", as well as the lack of conductivity between the terminals "Y" And "R".
3. Checking the interval change mode (INT).
A) Set voltmeter to DC range (D.C). Connect a voltmeter to the terminal "R", and the voltmeter to the output "C1".
b) Connect"+" battery to the output "+V", and the battery to the output "C1" (relay on (ON).
Voltage between terminals "R" And "C1" about 12 V.
V) From the position specified in paragraph (6), connect within 5 seconds short the leads "Y" And "L", and the relay from the position "ON" switch to position "OFF".
G) When removing the jumper from the terminals "Y" And "L", check that the voltage between the terminals "R" And "C1" is changing (0 V when jumper is removed and 12 V after 9-15 seconds).
