Sorted the CTek connection to the battery.
Next the power sources.
I have three requirements, satnav/music/phone charging and air compressor. The latter is not crucial so further down the line as never needed on my Morgans (yet). I did use it on another Morgan once when we spotted a slight low pressure.
Silly design issue....why enclose the usb power socket inside the glovebox? It was the same on the Plus8 with the cigar lighter style one. The glove box had to be open for satnav power or route the cable out behind the dashboard and looped round to the Garmin satnav. I haven’t checked the PlusFour yet to see if this is possible but the cable length may be a limiting factor. The bluetooth method for music device eliminates this so ok, but, connecting, say, my mobile phone for music/power source means glovebox access. I am not keen on enclosing a Li battery powered device in the closed glovebox and putting it in a cradle in view to use music selection or the Waze satnav as a back-up to the Garmin unit is preferable. I’ll have to check the options.
