TEST 9: Making Sure Ground Is Present At Female Terminal #2
In this section, we're gonna' make sure that female terminal number 2 is providing Ground to the radiator fan assembly.
The Ground that female terminal number 2 provides is for the high speed circuit of the radiator fan assembly.
To check for the presence of Ground we're gonna' do a simple multimeter voltage test.
These are the test steps:
- 1
Disconnect the radiator fan assembly's 4-wire connector.
- 2
Connect the red multimeter test lead to the battery positive access point on the Power Distribution Center.
- 3
Probe female terminal #2 with the black multimeter test lead.
The wire that connects to female terminal #2 is a black (BLK) wire. - 4
Your multimeter should read 10 to 12 Volts DC.
Let's analyze your test result:
CASE 1: Your multimeter registered 10 to 12 Volts. This is the correct test result and confirms that female terminal #1 is providing Ground.
You can conclude that the radiator fan assembly is bad and needs to be replaced if you have confirmed that:
- Both fan motors do not run in high speed when the high speed radiator fan relay is bypassed (TEST 4).
- Power is present in terminal #4 when the low speed radiator fan relay is bypassed (TEST 6).
- Ground is present in terminal #2 (this test section).
CASE 2: Your multimeter DID NOT register 10 to 12 Volts. Without Ground present at terminal #2 the fan motors will not run in high speed.
Your next step is to check the continuity of this Ground wire between the 4-wire connector and the battery negative (-) access point (located on the left strut tower). If the Ground wire is open, repair the problem and retest.
