GR8 BATTERY MANAGEMENT SYSTEM UPDATE
NOTE:
• You will need the IDS Laptop, MGSS access and the entire GR8 workstation, including the USB cable that is
included with the Midtronics GR-8, in order to complete the update.
• If the cable is missing, please purchase one from your local electronics store. Cable needs to be a regular USB
jack on one end and a mini
-USB jack on the other end. Do not install the cable until prompted to do so.
1. Plug your GR8 Workstation into a wall outlet.
2. Confirm the 6 AA batteries in the hand held unit are new.
3. Reinstall the hand held unit in its holder.
4. With the IDS Laptop, log onto MGSS, then select Special Service Tools & Current MRT List.
5. Click Here or select the GR-8 Update link below the GR-8 I-ELOOP Software Update title.
6. Select "Run" to download the Mazda(GR8-195E) file.
7. Select "Run" to install the Midtronics Update Wizard (MUW).
8. Follow the steps in the Midtronics Update Wizard to complete the 10-20 minute download.
Q85/T110 BATTERY VOLTAGE MEASUREMENT
Battery voltage can only be measured on a battery that has not been recently charged. If the battery was recently
charged, wait 6 hours or more before checking the battery voltage.
Is the battery voltage 12.4 volts or higher?
• Yes: The battery is charged.
• No: The battery requires charging. Proceed to Q85/T110 BATTERY TEST AND BATTERY CHARGING.

Q85/T110 BATTERY SPECIFIC GRAVITY MEASUREMENT
Battery condition can be ascertained using this method; however, the preferred method is to use the GR8 Battery
Management System. Refer to Q85/T110 BATTERY TEST AND BATTERY CHARGING.
1. Mix the electrolyte solution on all 6 cells by using a siphon to suction the electrolyte from the battery and then put it
back in.
2. Use a scope type specific gravity battery meter (refractometer) to measure all six cells.
Is the cell with lowest electrolyte specific gravity 1.25 or more?
• Yes: The battery is fully charged.
• No: Is the cell with lowest electrolyte specific gravity less than 1.17?
Yes: The battery may be faulty. If however, the battery is under warranty, you must use the Midtronics GR8 tester as it uses a more accurate method of testing. Proceed to Q85/Q110 BATTERY TEST AND
BATTERY CHARGING to accurately test the battery. If the Midtronics GR-8 tester fails the battery it will
generate a battery failure code for warranty claim submission.
No: The battery requires charging. Proceed to Q85/T110 BATTERY TEST AND BATTERY CHARGING.
