*If replacing a non-diode relay (original design) with a diode-version, it would be worthwhile double-checking the polarity of the connection to the relay coil to be sure it is compatible with the diode orientation. Where a diode is used, the positive power should reverse bias the diode when normally activated - this allows the bleed off of EMF energy in the reverse direction when the power is removed. | *If replacing a non-diode relay (original design) with a diode-version, it would be worthwhile double-checking the polarity of the connection to the relay coil to be sure it is compatible with the diode orientation.

- | *In the diagrams above I have included the standard HD connections polarity, as identified in the HD manuals & wiring diagrams, to allow comparison of that wiring to any proposed alternative relay. It appears to me, that many of the relays that include a diode provide positive power on the (86) contact while HD has wired (1991-1993 & 2010-2013) some of their relays with positive power on the (85) contact. Beware: I have not checked every alternative relay listed in the Sportsterpedia for this issue. | + | *In the diagrams above I have included the standard HD connections polarity, as identified in the HD manuals & wiring diagrams, to allow comparison of that wiring to any proposed alternative relay.

A home remedy is to use vinegar, which is a mild acid. It can be diluted in equal parts vinegar & water. You can use a toothbrush to apply on fuse/relay sockets, contacts, etc. Once clean, wash with water & dry (compressed air for crevices). Stubborn corrosion may require applying a paste of baking soda (and water). Let it soak into the corrosion and dry. Then brush & flush with water & dry with compressed air. | A home remedy is to use vinegar, which is a mild acid. It can be diluted in equal parts vinegar & water.

- | When the sockets or contacts are thoroughly clean & dry, apply a thin coating of dielectric grease ([[techtalk:ref:genmsr10#dielectric_grease|see here]]) to the contact surfaces, both the socket & the fuse/relay. The coating should be sufficient to protect the sufaces from air & moisture, but not oozing off onto other components. | + | When the sockets or contacts are thoroughly clean & dry, apply a thin coating of dielectric grease ([[techtalk:ref:genmsr17#dielectric_grease|see here]]) to the contact surfaces, both the socket & the fuse/relay.
