- Summary
- "issue: a customer may report a concern with a flat battery or poor starting; when testing the battery it is determined that a charge is required. Cause: when charging a battery (both primary and secondary) with a bms (battery monitoring system) fitted, the earth from the charger must be connected to a suitable chassis or engine earth (check topix for appropriate location). This allows the bms to see the current going into the battery. However when using a diagnostic charger from midtronics such as gr1, grx gr8(110 volts)this connection process can cause an incorrect battery analysis due to the extra resistance in the wiring when connected to a chassis or engine earth."
