A. Procedure

NOTE: Always obey the specific procedures and limits in the specific maintenance manual maintenance tasks.

NOTE: The electrical contact enhancer on the connector contacts in the connector interfaces decreases the intermittent signals that you think are not correct, and/or nuisance messages.

NOTE: The electrical contact enhancer is not an alternative to contact replacement. It is necessary to replace worn or damaged connectors as soon as the harness is at a location where it is possible to replace the connectors.

(1) Clean and dry the connectors, if the connectors are not clean or dry. Refer to Cleaning of the Electrical Wiring Harnesses and Contact Points (SPOP 6) (Ref. AMM TASK 70-70-00-910-803).
(2) Apply one drop of SPMC 205 electrical contact enhancer (Material No.P11-068) to the brush that the manufacturer supplies with the electrical contact enhancer, and then use the brush to apply a thin layer of the electrical contact enhancer to the electrical contact pins on the male connector of the mating pair of electrical connectors.

NOTE: Do not apply SPMC 205 electrical contact enhancer (Material No.P11-068) to the igniter high tension lead contacts, EGT harness connections, or EGT junction box connections. The temperature of these connections could increase to higher than 425 deg.F (218.33 deg.C) decomposition temperature of SPMC 205 electrical contact enhancer (Material No.P11-068) .

(a) If the ambient temperature is too cold for the electrical contact enhancer to flow sufficiently, add Reagent Grade P11-078alcohol, isopropyl to the SPMC 205 electrical contact enhancer (Material No.P11-068) in a proportion of 4/1 maximum (that is, four parts or less P11-078alcohol, isopropyl to one part electrical contact enhancer) to make the electrical contact enhancer more liquid.
(b) If you added alcohol to the electrical contact enhancer, let the applied electrical contact enhancer on the connector dry for one hour minimum before you connect the connectors.
(3) Connect the mating connectors (Ref. AMM TASK 70-70-00-910-802).
