The US Postal Service came through and delivered my new pickleball paddle Monday afternoon. I used it on Tuesday and Wednesday and I’m happy with it. The grip is very comfortable. The performance difference between this paddle and my old one is subtle – I expected a greater change. It gives good power and I feel like I have a little more control, but it’s not a night-and-day difference.
I crossed a couple more chores off my “to do” list this week. The first thing was addressing our vent fans. After studying the wiring schematic, I saw the power source ran from the fuse box behind the kick panel in front of the passenger seat all the way to the switch on the bathroom wall. It’s a 14-gauge wire with yellow insulation.
At one pole of the switch, another yellow wire is crimped to the connector with the power wire and runs back through the wall into the ceiling and goes to the kitchen vent fan switch. The other pole of the switch completes the circuit to the vent fan motor. This explains why both fans quit working at the same time. If current doesn’t reach the bathroom wall switch, then there’s no current going to the kitchen fan switch either.
Looking at the wall switch plate, I couldn’t see any fasteners. I carefully pried the plastic surround cover with a plastic wedge tool and popped the surround off. The surround cover was held to the actual switch plate with four tabs snapped into square holes on the switch plate.
With the surround cover off, I saw the screws holding the switch plate to the wall. With these screws removed, I accessed the wiring. I checked the yellow wires on the vent fan switch and found some interesting readings with my multimeter. At first I found about six to eight volts at the switch – meaning I had a large voltage drop from the 13.4 volts at the battery bank. I wiggled the wires and then read zero volts. I pulled the connector off the switch and checked the crimp and wire ends. I followed the wiring and found it coming out of the wall behind the clothes washer in the utility closet. I looked for breaks or abrasions in the wire and found none. I wiggled the wire where it enters the utility closet and pushed it into the wall opening to provide more slack. When I checked with the meter again, I read 13.4 volts.
Aha! Something was amiss with the wiring – there must be a break in the strands of wire and I had pushed them back together. The bad news is – the break must be in the section of wire inside the wall. I can’t just pull the wire out of the wall in the utility closet because the bundle of wires runs through plastic support loops every foot or so – including the portion inside the wall. They must have run the wires and secured the loops before the wall panel inside the closet was closed out.
I was stumped. I gave the wires another wiggle test and lost voltage. My thought was to splice into the wires for the bathroom lighting. I could make a short jumper wire and have a power source for the vent fans without running wires the length of the coach. To do this, I needed some 14-gauge wire and piggyback connectors. I put this project on hold to think it over before I bought the supplies and started splicing. I left it with the switch plate off and reconnected the wiring. Later, the fans came on – I had left the switches in the “on” position. I wiggled the wires again. The fans kept running. I left the fans on all day and they worked fine.
Before pickleball on Wednesday, I stopped at the auto parts store in Pacific Beach. I picked up some yellow 14-gauge wire and splice connectors. I also bought brake fluid for the Spyder. When I came home, I wiggled the wires again and the fans still worked. I decided to hold off on splicing into the other power supply wire and I put the switchplate and surround back together. I don’t like mystery fixes – I’m thinking some time down the road the wire will open again and the fans will lose power. I’ll wait until this happens before I splice the wires – I have what need to do it when the time comes.
Next on my list was the brake fluid level on the Spyder. Can-Am did some weird things when they designed the Spyder. The brake fluid is contained in a two-chamber reservoir with tubing supplying fluid to the master cylinder and hydraulic system. Vehicle master cylinders are dual acting mechanisms. There are separate circuits – in this case one circuit operates the rear brake and a second circuit operates the front brakes. Separating the hydraulics into two circuits adds a margin of safety. This is common practice on cars. Some cars – mostly European – take this approach to the next level by separating the circuits into a right front – left rear and left front – right rear to give greater braking control in the event of failure of one of the circuits.
Having separate front and rear circuits is all well and good on the Spyder design. The Spyder also has a fluid level sensor in the brake fluid reservoir. But the thing is, the sensor is way too sensitive. The slightest drop in fluid level triggers a brake warning light and the message “Brake Failure” flashes on the dash panel. It’s normal for the fluid level to drop slightly as the brake pads wear. The wear of the pads is taken up by the pistons in the caliper extending further in their bores. This creates more fluid volume in the caliper and it’s drawn out of the reservoir. On the Spyder, the brake fluid reservoir must be periodically topped up to avoid the dire “Brake Failure” warnings.
To make matters worse, they put the brake fluid reservoirs under the seat. The seat can be raised to access the reservoirs and battery, but it only raises a short distance – maybe a 30 degree angle – before it hits the stop.
The geniuses that designed the Spyder put the reservoirs at the back of the seat near the pivot point. There’s no way to get even the smallest brake fluid container in there to fill the reservoir. I poured a small amount of fluid into the bottle cap and added fluid one capfull at a time.
Last time I did this, I used a small syringe, but I didn’t have a clean syringe to use this time. Anyway, it’s job done. No more warning messages.
It’s time to head out and use my new paddle at the Pacific Beach Recreation Center. Earlier this week the forecast called for rain on Friday. Now the weather guessers say there’s only a 10 percent chance of rain through the weekend. Maybe we’ll play pickleball in Ocean Beach tomorrow.
