Flasher modules and Diodes on Nigel the 1977 MGB. How to test your diodes... Installed new Electronic Flasher units. #mgb #classiccar #wiring #customcars #1977 #electronic
The heater-based flasher units have one feature that the electronic flashers don't have. As you mentioned, does the heater-based flasher switches off when the element gets too hot, and switches on again after the temperature has cooled down. So the flashing rate ("blinks per minute") depends on the electrical current: if the current is large it will heat up quickly. If the current is low it heats up slowly. You can hear the difference in clicking sound. This is an easy way to recognise whether one of the light bulbs is broken: the current is suddenly less, so the flashing rate will be lower than usual. The electronic flasher units don't monitor the electrical current: they are simply time-based. So you can't audibly detect whether a bulb is blown or not. Vice versa: electronic flashers are required when the bulbs have been replaced by LEDs. The electrical current in the LEDs is too small for the heater-based flashers: the lights won't flash but will be on continuously.
Your comment may have just solved the issue I’m having with the ‘77 MGB I just bought. After a few minutes the turn signals stop working. The hazards always work which are on a different flasher relay. Thanks so much for making your comment 9 months ago!
I enjoy the info very much. However your constant use of errrm, aaah, arr very irritating. You should script each clip and stick to it. Otherwise it sounds as though you're not convinced about the subject.
Yup. Oddly enough, I give tutorials on professional speaking, and yet I find myself often making the same blunders I advise against. Fact is, I am actually just fiddling around in my garage. I seldom have a complete idea of what I will cover on a video. I do stage the parts, and do some post processing, but the rest is completely impromptu. I appreciate the feedback though. I will remind myself going forward to listen to myself through the audience's ears.
@@AlexPlatacis Eh, not that bad really. You come across as a parent showing their child how to do something and provide some information about how things work. I found that when my friends and I did a podcast, we all did the same, and when you are presented with the 'umm, er, ahh' you try to be more cognizant of the habit. The information you provide is still very good and the presentation is nice and friendly in manner, so I think I can say for most of us watching, it's all good!
