Voltage Regulator Upgrade

[brock]

A few of our guages operate on 5 volts. No, I don't know why. The
useage of a vibrator type voltage reducer was the normal solution
every since the move to a 12 volt operating system became the
standard.
Upgrades to this antiquated way include a simple voltage regulator
chip like a 7805. Be sure to include a heat sink! RTE also offers an
alternative that promises to be a plug-n-play solution.
Lets look at the original & RTE solutions side by side:




There is a grounding tab on the original that we need!


So just swap cases!

There is a little LED on the back of the RTE regulator. Any ideas on how to connect a piece of fibre optic cable to it for viewing from the drivers seat? I was thinking to just route it into the corner of another lightsocket or maybe below the bright indicator.

When does the LED come on? What does it indicate?

I should think a dab of clear LEXAL should do it...the link is an example. My local harware store has it. Dries truly clear, unlike a lot of "clear" silicones, which are cloudy/,milky when cured.

Got worried about the price of Lexal until I read the whole line: $47.88 Sold in multiples of 12 / $3.99 each.

5) There is a small LED that will flash when the limiter is operating properly. If the LED is off
all the time, it may mean that one or more of the gauges is shorted to ground. The limiter is
short circuit protected, and once the short is removed, then the limiter will resume operation.

It's actually odd to me that they would peak a customer's interest in an indicator & expect
them to crawl under the dash to view it But then again that whole "it may mean" part
makes me curious.
