CrimpWakespeed WS500 Alternator Regulator
Advanced external alternator regulator for high-output lithium charging. Drives the alternator's field with adaptive PID control and reports over J1939 CAN (RV-C / NMEA 2000), with a current shunt for charge monitoring. Supports 12–48 V systems. Powered from the battery through small fuses; carries no main charge current itself.

How the WS500 Regulator is wired
The run drawn here is the 10 ft reference run sized below. Sized against ABYC E-11 — the US reference, and what Transport Canada accepts as an alternative to TP 1332 for pleasure craft under 24 m. Confirm your own run length, routing and terminations before ordering — open this part in the designer to size it against your actual system.
What size cable and fuse does the WS500 Regulator need?
Sized against ABYC E-11 — the US reference, and what Transport Canada accepts as an alternative to TP 1332 for pleasure craft under 24 m. The design current is the part's continuous draw. The Crimp engine applies its ordinary continuous-load headroom, voltage-drop budget, terminal clamp, and standard fuse ladder. The 10 ft one-way run is a stated reference, not a universal installation prescription.

Catalog profile
The manufacturer, model, ratings and terminal map are maintained as planning data in Crimp's component catalog. Confirm the current manufacturer manual, exact revision and installed nameplate before ordering or wiring.
Engine reference
Sized against ABYC E-11 — the US reference, and what Transport Canada accepts as an alternative to TP 1332 for pleasure craft under 24 m. The published conductor, fuse and voltage-drop result uses the visible reference length and current basis; it is not a universal installation prescription.
