Pinpoint Test A: Voltage Drop

TEST CONDITIONS  DETAILS/RESULTS/ACTIONS 
A1: GROUND CIRCUIT 
NOTE: This test checks for high resistance between the battery terminal and the battery clamp
G00493310
Start the engine, turn on the following:
  • (1) Air conditioning
  • (2) Blower fan on full speed
  • (3) Headlights on main beam
  • (4) Heated screen - rear
  • (5) Heated screen - front (if installed)
  • (6) Heated seats (if installed)
  Connect the multimeter between the battery negative terminal and the battery clamp as shown in picture below (do not disconnect the battery at this stage)
Set the multimeter to read DC voltage and record the reading
Is reading equal to or below 0.1 volts?
Yes 
GO to A2.
No 
Switch all electrical loads and engine off, return the vehicle to an ignition off condition. Disconnect the battery negative clamp, clean clamp and terminal then reconnect and repeat test GO to A1.

The following steps must be carried out to ensure correct operation of the EXP-1080 during the battery test procedure

Checks  Action 
Battery fluid leakage, check for battery fluid leaks or damage to the battery casing
NOTE: If visible damage to the case is evident do not return battery under warranty
Replace the battery if there is any battery fluid leaks evident
Battery vent pipe routing Check for routing, ensure there are no kinks
EXP-1080 fly lead, condition of clamps Clean or replace as required
EXP-1080 fly lead connection Confirm secure connection
NOTE: The Midtronics EXP-1080 is suitable for testing flooded and absorbed glass mat (AGM) type batteries

Midtronics Battery Test Procedure

This midtronics battery test procedure will confirm the serviceability of the battery

Flooded Battery Care Point

If the vehicle is equipped with a flooded battery, ensure the replacement battery is a flooded battery of the same specification (cold cranking amperage (CCA) / amp hour rating (Ah)) as the original battery

Under no circumstances should you fit a flooded battery to a vehicle that originally had an AGM battery, unless formally instructed by Jaguar/Land Rover

AGM Battery Care Point

If the vehicle is equipped with an absorbed glass mat (AGM) battery, ensure the replacement battery is a AGM battery of the same specification (cold cranking amperage (CCA) / amp hour rating (Ah)) as the original battery, unless formally instructed by Jaguar/Land Rover
