Grove Nissan A15 Hydraulic & Electrical Schematics

A genuine 1993 Grove factory CAD drawing set (drawing 6-294-010482 electrical, E6-294-010983 hydraulic), title blocks read “GROVE NORTH AMERICA, DIV OF KIDDE INDUSTRIES INC.” Contains the full electrical schematic covering every engine option Grove offered on this platform family (Nissan A-15 gas/dual-fuel, Nissan H-20, Ford LRG4-2.5, Ford LRG4-23, Deutz F3L912D, Deutz F3L1011, Hatz 3L40C) with exact wire and solenoid numbers, plus the complete hydraulic schematic (valve bank, pump, cylinders, all functions).

The Nissan A-15 sheet also labels the fuel-side solenoids, “GASOLINE FUEL SOL 24” and “ANTI-DIESEL SOL 27” (page 9), and the hydraulic sheet (page 10) shows the full multi-function valve bank — steer, propel, lift, telescope, swing, platform rotate, platform level — matching the hydraulic manifold identified in the parts catalog. See My Story for the hydraulic coil this resolved.

This document’s title blocks read “AMZ66/56” — the articulating-boom family — not MZ66B by name. It is not confirmed model-exact the way the sales brochure is. The Nissan A-15 engine circuit and the hydraulic valve-bank architecture are very likely shared verbatim across Grove’s whole Manlift line (the drawing itself references other engine/model sheets, consistent with a shared multi-model reference set), but treat any AMZ-specific boom-function wiring or cylinder dimensions as unconfirmed for the MZ66B specifically — cross-check against the parts catalog before relying on boom-specific numbers.
