Buck Boost 100amp Not Charging.

Hi All,

so i have fitted over ten of these units to brand new merc vitos over the last 6 months, how ever i have run in to an issue with one of my latest installs.

the Buck boost is fitted to a connect 6 bus bar via a fuse (fuse tested and fine ) to charge 5 x 12v LiPo4 victron smart batteries totalling 1000ah

all programmed the same as all the others, it is set to 75amp at 14.2v with the victron Lithium ticked.

basically, it starts charging as it should, and checked outputs on TSconfig with Buck running and it is kicking out 75amp on the screen however it is not actually giving any real output!

also another weird symptom is that when it is connected it will intermittently cause the engine to cut whilst driving. if i remove the input fuse to the buck this symptom does not occur.

has anybody else come across this issue?

the vito alternator is a 190amp.

as a general rule they usually give a % increase of around 8% per hour when charging.
