[Healeys] wiring or testing of electronic Tach question , testing of fuel gauge

[BJ8Healeys]

Jerry, attached is a photo showing the correct loop direction for negative
ground.

There is a bench test process for the fuel gauge, although it's for an MG,
at: http://mgaguru.com/mgtech/electric/fg_06.htm

The test procedures for the Healey and MG gauges are the same, although Mo
Ma told me the Smiths gauges should be seeing about 90 ohms when registering
full, rather than 68 ohms as the above procedure gives.

If you decide after the bench check to try to calibrate it yourself, get
back to me because there are some cautions you should observe to avoid
damaging the gauge.

Could someone tell me about which direction the white wire wraps around the
post on the electronic tach?  Clockwise or counter clockwise?  This has been
converted to neg ground!


Is there a bench test for the BJ8 fuel gauge?   I measure 62 ohms across the
connectors.


Thanks for your help.
