"Resistance & Diode check Batt+ WIRE to Reed Switch in
Resistance & Diode check Batt- WIRE to Reed Switch in
Resistance & Diode check Batt+ to Control Box
Resistance & Diode check Batt- to Control Box
Resistance & Diode check - Motor to Reed In
The tests above are simply "Black Boxing" to confirm quiet relay or solid state "guts". Resistances should nearly be the same no matter the lead polarity. Diode Check, sometimes to often not."


The above was requested from a prior post.

control box is sealed and one cannot get inside to test anything. I purchased a dmm. readings are as follows as best I can do.

with meter set on diode check mode and battery and motor disconnected
( 1 seems to be default mode of display on meter).:

batt+ to reed + reading 611
batt neg to reed either side, no response
batt to control box, cannot access
motor + or neg to reed in 1
motor neg to reed neg 79
batt + to motor 1
batt neg to motor neg 001

 

What kind of multimeter did you get?

a "1" often means "out of range". Is it an autoranging meter, or does it have a dial that lets you select the voltage/resistance range?

When in resistance, the 1xxx is the same as "open", depending on your meter.

 

I used the 10 amp level and got my amperage. Then, Thatoneguy helped me find and choose reed switches...

Thank you for your help...

problem solved. MK

 

Current was 150mA through coil, he found a 1/2A reed relay and magnet that will fit in his mount.

Last problem is saltwater-proofing, but he has worked with that in the past.

Does anybody have tips for under-saltwater disconnects? I'm 1,000 miles from the nearest ocean, so haven't had frequent direct experience.
