A few minor updates have been made after not touching the car for a few months while another project was taking priority and blocking the driveway. It came right to life with the only issue being the coin-cell battery that maintains the dashboard clock needed replacing. The rest of the systems woke right up.
Heater + Brake setting
Discovered that when the heater is on, it introduces about 0.3v rise (0.5v-->0.8v) in the analog brake signal going to the Sevcon controller from the brake-line presssure sensor. This was enough to exceed the starting voltage for braking and thus when the heater was on, the controller would not engage the traction motor from a stop. Raising the start voltage for the regenerative braking to 1V was sufficient margin to avoid this issue without impacting the brake responsiveness.
Front Driving Lights and Turn Indicators
After 10 years of use, one of the front turn lights stopped working. Easy to replace both and the LED bulbs have improved significantly in 10 years. Selected Phinlion White Amber Dual Color 1157 bulbs with projector. Very bright now!
Hazard Switch
As reported elsewhere, the Classic Mini Hazard switch is a maintenance item, and I guess after 50 years, the original's time finally came up. One of the tab connectors broke spontaneously, leaving hazards inoperable. After attempting re-attach the wire, the switch is still inconsistent. Since this switch also controls the turn-indicators, it is a critical component. There does not seem to be replacements available with the tabs,only barrels, since this switch was primarily used in Canada during the early 1970's. I am attempting to "refurbish" the switch to nurse a few more years out of it.
Other tweaks
Notice a subtle oscillation when starting out from a stop-sign. Lowering the proportional gain Kp from 2.5 to 2.2 to see if that will eliminate the oscillation.
