billrigsby Posted August 21, 2020 Report Posted August 21, 2020 (edited) Was going through some electrical items today - running tests. Seems the heater and wiper motor are OK, posted pics of the harness earlier, not too bad. Radio, not so much, it will take some looking at. ☹️ Question on the wiper motor switch, I am wondering just what this is...... Checked the manual and parts list to no avail? As far as the radio, I did bypass the Spark Plate as the Spark Coil came disconnected from it, but that should have no impact on function (based on my 4 years of HS Electronics classes)? It is basically called a Capacitor in the radio manual? Thanks, Bill Edited August 21, 2020 by billrigsby Quote
JBNeal Posted August 22, 2020 Report Posted August 22, 2020 I believe that contact breaker whatzit has something to do with completing the wiper cycle so the blades park only at the rest position if the switch is turned off during an arm sweep 1 Quote

If I remember right it was the only protection on earlier ones...then they added a separate CB but kept that....idk why. Quote
