Modern 3 prong flasher
 

Ok so my really good flasher gave up the ghost and replaced it with one of the modern ones sold by Snyder's. Now instead of going flash...flash...flash it goes flashflashflash. It's a standard 6 volt system and bulbs. While this is on both my Model T and 48 F2 (I have the same flashers right now on both and both are doing the same), do I need to install a resister on the power input or?

Thanks

You probably need a heavy duty flasher.

Did you check the blinker fluid?

I know we all heard it before but I had to do it

Re: Modern 3 prong flasher
 

I assume you're talking about a 535. I'd recommend finding a new old unit on eBay or some such place. These new ones are pretty much junk.

Re: Modern 3 prong flasher
 

I bought one on ebay that went flashflashflash. Ordered one from Snyder's and it behaves like it should. Luck of the draw, I guess. Pry open the aluminum cover with a pocket knife and try to adjust the spacing between the copper contacts to the L terminal. Might help.

I pried one open and was surprised to find NO mechanical contacts, but to separate solid state circuits. One for positive ground, one for negative ground.

The 25.00 one from bratton's solved my hyper flash issue, I an 6 volts and all LEDS all around, headlights, tail lights and 3rd brake light.

Where did you get the LED headlights and do you like them?

BV535 is the flasher for 6 volt pos grnd vehicles! Is the flasher from Snyders Pos or Neg ground? I think Amazon sells both types!

Re: Modern 3 prong flasher
 

535 flashers are nonpolar, despite what know-nothing stuff sellers may claim. The one from Snyder's works fine on 6V positive ground. Should work on negative ground as well.

Re: Modern 3 prong flasher
 

Sadly, I thought the same thing as you, but in this modern world, there are now some solid state flashers showing up replacing the old vintage thermal flashers. (and they need to be wired to match how they work, which in a way makes them polarized in need.) I would venture Snyders is aware and has a thermal flasher replacement, that does not care.

Re: Modern 3 prong flasher
 

I should add, the T is negative ground and the 48 positive ground. As both work the same, that would tell me that they do not care what ground is used.

Re: Modern 3 prong flasher
 

You're right. I was back in Tung-Sol world.

The newer ones have a transistor to switch the pilot lamp. Apparently Chinese labor is cheaper than an extra contact on the armature. I think these will work with the opposite polarity, except the pilot won't, and it will likely puff the transistor.

For me personally, I still use hand signals! But I do little night driving! Tung sol, those are words I have not heard in a while!

Re: Modern 3 prong flasher
 

My pilot light works fine with both negative and positive grounds and nether have gone poof!

Re: Modern 3 prong flasher
 

Are they Tung-Sol flashers?
The one from Bratton's looks to be a good replacement, but pricey...
I've seen only two 6-volt positive ground electronic flashers, but they both said "up to 1-1/2 seconds before first flash." Not for me.

Re: Modern 3 prong flasher
 

The units installed are described above, from Snyder's.

Re: Modern 3 prong flasher
 

Sorry, I understood you to say you replaced only one. I'd call Snyder's and let them know your new flashers are bad, they don't want to be known for selling junk. I'm sure they will replace them. Just be sure you have no blown bulbs or broken wires. (Just sayin' - I've had to eat crow more than once.)

There is absolutely no way to make crow taste good. Nasty critters. I have a feeling thats where the term came from. [smiley face]
