Forklift Main Control Box: Confirm the Electrical System Before Replacement
A main control box may distribute power, relays, fuses or control signals, but the name alone does not define its internal circuit. HZK189 and part number 1403640301 must be checked together with the truck configuration and connectors.

Use the label, connector arrangement and truck electrical system together; the housing alone cannot confirm compatibility.
Request this control box
Confirm voltage, connectors, production version and any programming requirement before supply.
Send my truck detailsFault reported
No power, intermittent shutdown, several dead functions, repeated fuse failure or communication faults may involve the control box, but also the battery, key switch, contactor, wiring, grounds or connected controller.
Confirm the fault
Record fault codes and operating conditions. Check supply voltage under load, grounds, fuses, relays, connector pins, moisture and heat damage. Do not replace an electronic box until external power and wiring faults are excluded.
Identify the exact unit
Send the complete label, 1403640301 reference, HZK189 marking, truck model and serial number, voltage, connector photos and any software or production-version information shown on the old unit.
Choose the supply level
Genuine supply is the safer choice when circuit design, firmware or pin assignment is not independently documented. A replacement unit must have traceable hardware and software identity—not merely a matching housing.
Compare the same scope
Confirm whether the quotation includes the complete box, relays, fuses, mounting hardware and required programming. New, repaired and exchange units must not be compared as if they were the same condition.
Confirm before dispatch
We record the actual product, label, connectors and supply condition against the approved reference before shipment. Programming requirements must be stated before the order is finalized.

| Identity | Part number, HZK marking and every label on the old box |
| Truck configuration | Brand, model, serial number, voltage and controller arrangement |
| Supply condition | New genuine, traceable replacement, repaired or exchange unit |
| Commissioning | Any coding, parameter loading or installation procedure required |
Send the box label, connectors and truck information
Include the fault description and codes, old unit photos, truck model and serial number, voltage and quantity.
Main control box HZK189, checked before quotation.
The supplied label identifies this HELI main control box as part number 1403640301, reference HZK189. It is presented for buyers replacing a control box on an electric forklift.
A control box can look correct and still differ in connector layout or truck configuration. We check the label, harness connections and forklift identity before confirming supply.

Important main control box reminder
A main control box is matched by its electrical functions, not by box size. The HZK189 reference must agree with the truck voltage, connected devices, connector layout and internal control configuration.
Before quotation, our parts team checks:
Why this component needs a careful match
The correct control box must communicate with the truck wiring and control architecture. Matching only the housing or a similar label can create a non-working replacement.
Reference first
1403640301 and HZK189 are checked against the request, not quoted from a generic control-box description.
Connector detail
Harness plugs, branch layout and mounting details help distinguish visually similar control boxes.
Responsible quotation
If the truck identity is incomplete, we tell you what is still needed before confirming the part.
Accurate quotation
What to send
Send the information you already have. Our parts team will check it before preparing the quotation.
- Forklift brand, model and serial number
- Control-box nameplate or old-part photo
- Clear photos of each harness connector
- Quantity and required delivery time
