Thanks to all for the participation. And most of all to Gordon for a long ride, albeit in nice weather, but with high winds.
I got across the border about 3 and got to Escondido after a nice dinner in Julian.
Like I told Gordon, next time is my turn to go for the rescue.
I'm tempted to buy two controllers, but if there is a new one out, according to DR, maybe this is one that won't be so failure prone.
If someone else wants to buy a new one, I'll purchase the old unit still working to carry as a spare, for someone else.
I was carrying all the tools I needed which really is just a small kit.
DR is also right about space to change the unit.
At first when it stalled out in Tecate, I was able to pull to the side of the street and into a parking lot.
But on 2D to the east, first I had a very small shoulder, on a steep incline, against a rock wall. But after a while it fired up and I got 20 miles further. Then I was able to pull into a rest area/overlook so I had real nice scenery. Til dark, when I had to walk down the road, no shoulder, speeding downhill traffic to a blue phone. Almost immediately two guys with a trailer showed up and hauled me into Mexicali, near the border crossing.
In all fairness, I had an offer on advrider also. Bruce, in El Centro, offered a trailer, garage, and he could cross the border or whatever was needed.
