[Healeys] BN1 turn signal problem

[Healey100M at gmail.com (Randy Hicks)]

Hi, got a non-list friend who is being driven nuts with his front turn
signals. Rear directionals work fine, but fronts both flash regardless of
which is indicated. Any ideas why?

Early BN1, new harness, new flasher unit and relay (gaps are fine), rebuilt
trafficator, and wiring is hooked up by diagram.

Any ideas would help.

TIA.

Randy
