DA7000 Voltage Diagnostic

This documentation can be used as a guide when inspecting and diagnosing failure associated with the AC

voltage output on the DA7000 series generator.

Use of an accurate multi

meter is necessary when inspecting the generator.

Safety precautions should be followed at all times when servicing this

equipment. Consult operations manual for more safety information.

Inspection Procedure

Check the following with the engine off!

•Inspect F4 fuse, (see page 3).

•Inspect (J) terminal on TB2 for 12V DC when starter switch key is in the run position, (see page 3).

Starter Switch

( MQ part# )

3741059110

•Inspect for loose wires, contacts, or damaged receptacles, starter switch, & circuit breakers.

•Remove J-K bottom yellow wires from TB2 (stator excitation windings) perform a resistance test, (see page 3).

…………………………………. .Resistance specification: 1.63 ohms

•Perform a resistance test between stator windings wires U1 to V1 and U2 to V2 …

Resistance specification: .16 ohms (located at TB1)

•NOTE: Before performing resistance test always disconnect and isolate the wires to be tested. Resistance

(nominal reading ± 10%)). When checking resistance also check each wire for continuity to ground for open

circuits.

•Inspect RE1 diode rectifier for continuity/no continuity as shown below.

(Disconnect the leads to properly check the rectifier & resistor)

Technical Information

RE1 & R

Resistor &

Rectifier

RE1 & R is mounted behind the panel by machined screws

RE1

There are two rectifiers at this location, the top one RE1 is for excitation.

RE1

(Diode Rectifier)

( MQ part# 0601823204 )

prevents voltage spikes or back feed in the circu

it.

(Resistor)

( MQ part# 0601842463 )

opposes the electrical current by producing a voltage drop

between it’s terminals in proportion to the current. (controls the flow of electrical current)
