Recently fitted to my K75 an Acewell 4454 instrument connected it to a Maru-Labs bep3.0.
Experiencing some problems:-
Tach needle fluctuates. Not steady. Also seems to overead. It’s connected to the bep 3 RPM output. I have also tried fitting the supplied 100 ohm resistor. Then rpm ceases to function.
Now want to connect tach directly to no. 1 ignition coil as suggested in Acewell 4454 user manual. Not sure which wire to connect directly to on ignition coil.
Can I wire to any of the other ignition coils?
I have also wired 4 separate led warning indicator lights connected to the outputs of the bep 3:-
WRN. my led does not switch on when ignition is switched on.
BAR. This led switches on when fuel level is 4Litres and lower. ( working)
ALT. Not sure how to use this function. I had a led light connected to to this output. When bike is running light remains on.
CHK. My led light does not switch on when choke is activated.
TMP. I have a led light connected to this output. Hope it will switch on if there is an over temp situation.
I still need to fit the supplied water temp sensor. The thread of the sensor is 1/8”npt and will not fit the thread of the drain plug in the water pump housing which is M10x1. Will need to source a suitable adapter. I’m also considering an adapter which will fit into small hose that is behind radiator. What is inside diameter of that hose?
