22) R37 and R38 are 'sense' resistors for the current limiting circuits on the injector drivers. Normally these
should be installed.
(If, however, you prefer to do without the current limiting and want to make two spaces on the heatsink bar,
then you can instead link out R37 and R38 by soldering a copper wire between the 2 holes in each. Ensure the
link is flat to the board as you may need a component on the heat sink later on in the build. Remember that
without these current sense resistors, there is no over-current protection on the injector circuits.)
Note: I installed R37 and R38
23) R43 is intended to allow coil current to be measured if you are using the Q16 high current coil driver.
Unless you have access to an oscilloscope and plan on performing this test you won't need it. Either install R43
or link it out. Most people seem to leave it out without the link, so this is what I’ve done.
Testing Stage:
24) The board is now built to a basic level and is ready for a few tests:
