Tt 550 not holding charge when on bike
Tt charges ok on computer
So I put a fully charged sat on my bike and head off, all seems good nav setting say tt charging, but after about 3-4 hours tt flat even though indicates still charging
I’ve wired using a relay with switched wire to turn relay on/off ground is direct to battery, I’ve 5.5 volts across the pins
Please help this is doing my head in ha ha

SuperuserWithout measurements you can't really tell what's going on. Voltage (potential difference) alone is half of the story. You must also measure current (rate of flow) as well.
In charging circuits there are diodes that protects the battery from discharging.
Anyway, connect the charging dock directly to the battery and see what happens.

Welcome to the site....
@Have you checked the power pins on the Rider Mount... they should be free in the mount, protrude 1.5mm and be spring loaded
Is the Mount & Rider 5xx stable when the Bike is running/ticking over etc... (i.e Vibrations V-Twin or Single Cylinder engines) this can cause an intermittent power connection.....
Does the bike use the CAN bus Wiring System... You can get weird results tapping into a CAN bus System....
