Hall Sensor discontinued by manufacturer Posted by walt [Email] (#2707) [Profile/Gallery] (more from walt) on Fri, 25 May 2012 07:51:18 In Reply to: Hall sensor, ahealey56 [Profile/Gallery] , Thu, 24 May 2012 18:13:48 Members do not see ads below this line. - Help Keep This Site Online - Signup |
The 4AV18F hall sensor used in the crank pulley sensor is discontinued by Honeywell per Mouser (see link). It might be easier to just get a distributor with hall sensor connector on the side and 3 foot wire connected to it and eliminate crank sensor. Inside the distributor, wire colors match colors on engine crank sensor harness. Black to black, red to red, and yellow to red/green. On a two-wire distributor connector, use the shield as the black wire. The harness end of the distributor connector wire will need a female gray 3-wire connector with male pins. If connector is not available, it could be converted to a 4 pin Molex connector, obtainable from RadioShack. The EZK ignition controls timing at 14 degrees at idle, but should be timed statically at 5 degrees by setting flywheel timing mark to 5 degrees, then twisting distributor body while watching switch voltage (red/green wire with reference to black wire) from hall sensor. Watching the voltage only works while connector is plugged into engine harness with ignition ON and engine not running (but leave in Park or Neutral). If a turbo distributor is used, leave vacuum hose off the distributor vacuum can, since EZK adjusts timing based on knock sensor, without needing vacuum advance at distributor. The biggest difficulty may be finding a distributor with a hall plastic connector that is not falling apart, which is more of a problem with turbo cars. If not too bad, plastic may be repairable with an epoxy.
