Thats a DIFFERENT STUFF. All my explanation is based on cars still with ammeters in working order and also explaining how ammeter can be kept in place still with upgrades and safe.

The installation you posted is exactly the kind one which, on stock setup, acelerated the bulkhead burning process along the years and get ammeters out of their limits, being constantly stressed.

Now, bypassing ammeter and bulkhead at the same time with the tipical batt/alt jumper wire is, as told by John is a matter of prefferences, but even this must be made on the right way.
