Ottawa Weekend protected by Armed Guard

I took off to Ottawa this Canada Day weekend on my motorcycle accompanied by some good friends, Dave and Derek. We drove highway 17 most of the way from North Bay and rode HW 148 from Pembroke to Hull. For a bike this is a scenic, safe route because the HW speeds are slower, there is less traffic and its two lanes the whole way.
No Queens way to deal with too!

Dave and Derek on the Bikes

It was late when we arrived and I wasn’t exactly making the best driving decisions as I tried to figure out the route to take to get to Dan and Nicole’s. Lets just say that I lost Dave and I luck would have it, I ran into Jen and Amy taking the same exit, at the same time, driving in the CRV. What are the odds! Anyway Jen went and found Lost Dave.

It was a great weekend, lots of BBQ and Beers… of course with the bikes parked. We traveled the same way home and took our time. Here is a picture of the covered bridge in Fort- Cologne, QB

I forgot to mention that I recently equipped my alarm with an additional Siren. The new Siren is meant to be much louder and more effective. An alarm is essential for a good nights rest seeing that you don’t have to get up and check for you bike ever hour so the louder the alarm, the better.

While I was in Hull my alarm malfunctioned. I set if off and I could not turn it off with the remote. It was loud and starting to hurt my ears. I had to lift the seat and unplug the whole device. Crap… the new siren must have drawn too much current and fried the unit.
Every time I plug it in it still goes off.

Where you left off

I tried replacing the remote batteries but that did not work. Whats funny is that Canadian tire sells the 2016 3v watch batteries for 4.99 each. I needed 2 of them. Instead of paying that I bought a little keychain LED light which has the same batteries in it. I paid 5.99 instead and got what I needed plus a light. But as I mentioned, the batteries were not the problem.
I opened up the alarm and I noticed that one of the small transistors had a mark on it. It was the closest to the where I had attracted the second siren. A transistor is a small electronic switch. I figured that it must have fried open which would explain why the alarm is always on when I plug it in. A few continuity tests confirmed it. I ran voltage through both sides meaning it was open. I should have only been able to run voltage through one side.
Since that is an important transistor, and hopefully some other transistors that meet the same specs are not as important I’ll try a swap. IT WORKED!!!!! I unsoldered and re-soldered two transistors to make the swap and now the alarm shuts off and I can arm it and dis-arm it. Wonder what that other transistor really did?

Still not done yet. Since the new siren requires more voltage I’ll have to add a relay. The alarm will tell the relay when it’s on and the relay, using a separate power source, will tell the alarm to turn on. This will solve the problem of the new siren drawing too many volts and popping little transistors. Honestly, there was a 1-1000 shot that I could ever fix something like this.

Chirp-Chirp. Now don’t touch the bike… I can’t afford a new alarm.

I swapped the transister in the picture above. They were the same specification so their resistance and tolerance are identical. The swap would not work if I used a transister with different specs. I almost didn’t get the first one soldered back on… it was tricky.
