Shumacher 10 amp automatic no output model se40M

There is a 1335 Farm and Ranch charger that is 200 amp. The 1235 does not say it is Farm and Ranch on the face, and is a 100 amp charger although automatic. It looks different from the 1335. I don't find a manual or the charger currently for sale on the Shumacher page but I do find you can download a manual for the SC1308 there and it physically looks like the fro1235, has the same interface controls, and is a 100 amp charger like the fro1235. I suspect the directions are the same for the interface. I have read consuer messages saying these manuals are confusing. If such is the case, you can try the customer service contact at the website. That said, these are supposed to be automatic and to not work if connectd to the wrong terminals by design. https://www.schumacherelectric.com/products/100a-6v-12v-fully-automatic-battery-charger-engine-starter/#manualTutorials

Batteries can be charged parallel using the correct voltage but it's always better to charge them independently. This allows you to better evaluate the battery condition as well as making it easier to identify problem cells.

My suggestion is to never use the 100 amp start except when you have someone to crank the engine while you operate the charger. You really don't want to pump 100 amps into the battery unsupervised, it could explode if frozen and may even have other issues.

The 30 amp boost is a quick charge. Your best setting is the 6 amp which will build back the voltage gradually. The 2 amp is the slowest charge, some folks use this for deep cycle charging marine batteries and just when you are in no hurry to use the battery.

hello
u'd need a proper manual for this in my opinion
like there are plenty of dealers an d online shops that deal in those..
you can get some free at sites reliable-store.
and it;s actually really illustrative

Hello Hermando, I assume your truck battery is 12 volt. You would want to select 12v 2a for a long slow charge or 12v 6a for a shorter faster charge.

Hello there.

You need to ask again but give make AND model number details of what speakers and Amps you have and how configured / connected/

First thoughts from what you say are Overload / OverHEAT of Amplifier output Stages so Automatic shutdown of Amp until cooled..

Keep 'em Cool and DONT overload Amp inputs.

Search for 3-position rocker switch
Use google and google image search.
Quick search shows 16 amp switches.
Probably the switches inside charger control contactor or relay.
Or connect directly to a circuit board.
The board might be bad, or relay points burned.

The SE40MAP has an automatic shutoff when battery is fully charged.

yes it could be

check your battery 1st , then check the stator a/c output

• 10 or 16 Amps DC regulated for charging
battery
• Two black leads (C) from stator
• Yellow connector (D) with two pin
terminals
• Two yellow leads (E) to regulator-rectifier
(F)
• One red lead (B) from regulator-rectifier
to red connector output lead (A)
• 10 and 16 Amp systems use the same
stator, color coding and regulator-rectifier
• Alternator output is determined by the
flywheel alternator magnet size


The stator and regulator-rectifier are the same
for the 10 and 16 Amp systems. The system
output is determined by the flywheel magnet
size.
Test Alternator Output
1. Temporarily disconnect stator wire
harness from the regulator-rectifier.
2. Insert RED test lead (A, Figure 28) into the
V ω receptacle in the meter.
3. Insert BLACK test lead (B) into COM
receptacle.
4. Rotate selector to AC Volts position.
5. Insert RED (A) and BLACK (B) test lead
probes into output terminals (D & E) in
YELLOW connector (C). (Test clip leads
may be attached to either terminal).
6. With the engine running at 3600 rpm, the
output should be no less than:
• 20 volts - 10 Amp System
• 30 volts - 16 Amp System
7. If No or Low output is found, check for
bare wires or other defects. If wiring
defects are not found, replace the stator.
voltage depending on alternator type and magnet size

then check the regulator / rectifier , make sure it is grounded properly

make sure battery earth lead is good

i suspect loss of bat voltage is letting the afterfire solenoid close off the main jet

let me know model and type codes off engine & i will try help further

cheers

Soo sorry, unit is DEAD.
