M1009 wait light/glow plug card issue

Maybe not as great as a solargizer, but definitely cheaper would be an analog battery charger. Plus, you can use them to get rid of rust! Stovebolt Tech Tip -- Antique Chevy / GMC Truck Restoration Help

If I replace the Glow Plud Relay that is there with the, BWD S603
from O'reilly, will that be a good enough replacement?
Because O'reilly has it for $39.99..
And Napa has the ECH ST85 for about $61.00...

No matter which relay you use, be sure to test and verify that the small terminals are electrically isolated from the case / mounting lugs of the relay housing. The parts house where you buy the relay will probably have a VOM / DVM to use and can show you how to test it using an ohms measurement. There should be NO continuity between the smaller terminals and the case / mounting lugs.

Do not assume that because the box has the correct / expected part number on it that the relay is in fact isolated. Test it for yourself!

You can check *bay mine was $189.00 for the good one and they have some decent ones for $65.00. My optimas are the miliary conversion that came with the plastic trays that bolt onto the original trays that the batteries just slide and snap into.

By the way, I looked at the solargizer on their website,
you are right it is roughly $519.00.
So I will be doing that upgrade when I have $519.00 to spend

My 1009 developed these symptoms a few weeks ago and this thread helped me understand what may be the culprit.

Turn key on, wait for the light and fire it up. About 15-20 seconds later, the voltmeter will move over into the green and then for a couple of seconds, a few things happen simultaneously; wait light flickers, voltmeter clicks back and forth wildly and you get the buzzing sound from behind the firewall. Once the buzzing stops, all systems go back to normal and everything seems just fine.

My relay looks to be identical to the Ecklin (NAPA ST85?) in the photo here ...

Looks new ... pretty sure it was changed before I bought it last November ... will check it out to see if it passes the tests.
