So a little explanation here. I have witnessed while driving a car , a motorcycle going down the 401 highway, not a care in the world, beautiful sunny day, apparently he is turning right at any moment, at least he was 5 KM ago and apparently is just looking for that exit. Well I have had it happen, coming over a rise in the road, hitting 8k , up-shifting like crazy , need to boot it home, just turned right onto the road, not paying attention as my tank bag kind of hides the signal light blinker on the dash. I see a guy to my right stopped at a stop sign, getting concerned cause I am just 15 over the speed limit and it appears he is going to pull out. Fortunately he realizes at the speed I am going, no way could I make the right turn my signal light is telling him, yes just then I realize , OH S**T , and cancel the signal light. So I have had this sonic sensor for at least 25 years and at least 5 or 6 bikes ago, each time, yup going to install it. So last week I did that but realized I need a complicated circuit , as I don't want to hear beep beep beep beep for 3 or 6 minutes while I am waiting for the light to change. I have a very special and a very cheap programmable timer coming from China. I am looking at a 3 minute delay on operate. Since the signal is intermittent , the timer needs to acknowledge this intermittent time , yet use the actual time elapsed at a set point , in this case of 3 minutes. So I stuck it in, put some wire on it, and left it.
Today while walking the dog, I had cleared my brain, and it hit me, 90% of the time, my signal light is on while I am stopped, waiting at a stop sign or stop light. So I now have my sonic alarm active, with provisions to add the timer when it gets here.
So a number of things. I have a rework solder station, I still do some personal rework on control boards. Since I am retired, my electronic suppliers are no longer accessible, has to me as a private citizen . That became apparent in 2019 when a local large electronics supplier had a notice when I got to check out, minimum order $100 plus shipping. NFW. So I have a list of electronic suppliers that sell to individuals and ship to Canada. I ordered something like 13 Omron PCB relays , all special configuration, with shipping to my door, something like $56 . I got it in like 5 days. There are other suppliers like Sayal or Princess auto , but when it comes to basic electronic parts Diggi-Key is excellent, also a few others.
So if there is interest I will add this to How To and add more info. For now here it is.
to the left of the TPM-- Sonic Alarm
This relay came with my Denali light kit, it was SPST but only wired using the normally open contact #30 & 87 , I removed the connector and wiring and made my own harness, that is a socket and relay , originally I was going to use one of the 13 PCB relays I removed from my Haier PCB , unfortunately they were SP ST and DPST, no NC . So I am using #30 & 87A of that relay. The sonic alarm will sound for the same amount of time that the signal light is on, since the current is something like 0.0125 amp at 14 volts, that is nothing.
I have a mistake I have BR as in bridge rectifier , but I also have BR as brake relay. So the brake relay has contact # 30 & 87A and coil circuit 85 & 86
Note also that many times mass produced items are cheaper than less used devices. Rectifier diodes are generally available in 1 and 2 amp ratings. I have a multitude of 25 and 30 amp bridge rectifiers . I designed a special ground fault device for large carbon arc Miller gouging welders, that are no longer made, they put out 2000 amp continuous. The issue was these were mounted remote, a common occurrence was having the work electrode which was attached to a steel plate, come in contact with the steel building structure, so someone bringing a casting on a crane, well it was arc time, many times the 1 inch steel airline had a hole blown in it, the 200 HP compressors couldn't keep up and of course the shut off valve needed a lift or extension ladder to reach. So I have some left over parts .Those bridge rectifiers can have a standard spade female terminal attached , no soldering required.
