Decades old but unused and in perfect condition – no corrosion, no burnt contacts, no cracked Bakelite housing, terminals clean and straight, internal components untouched, no signs of heat damage or previous use. \*\*Bosch Part Number:\*\* 0 190 600 016 / 0190600016 / 0190 600 016 \*\*Description & Function\*\* This is the classic \*\*Bosch 4TR-style voltage regulator\*\* used in many 1960s–1970s European classic cars with Lucas or Bosch dynamo (generator) charging systems (pre-alternator era). It mounts in the engine bay or under the dash and regulates dynamo output to maintain correct battery charging voltage (~14.2–14.8V), while providing cut-out protection to prevent battery discharge when the engine is off. The 4 terminals are typically: A (armature/dynamo), F (field), A1 (to battery/load), and D (dummy/earth on some setups). Very common failure on vintage Mercedes, Porsche, BMW, VW, and other Bosch/Lucas-equipped classics — symptoms when bad include: \- Battery not charging (low or dead battery after driving) \- Overcharging (boiling battery, burnt bulbs, high voltage) \- Charging light stays on or flickers \- Dynamo runs constantly or not at all \- Electrical system faults (dim lights, weak horn, etc.) \*\*Key Features\*\* \- \*\*Genuine Bosch OEM\*\* – original equipment supplier for Mercedes, Porsche, BMW, VW & many classics \- New Old Stock – \*\*NOS\*\* – never mounted or used \- Correct factory Bakelite housing with Bosch branding and 4-terminal layout \- Original internal points, coils, and bimetallic strip for precise regulation \- Direct replacement – bolts to original location with correct wiring \- Ideal for concours restorations, purists, or anyone wanting factory-correct charging system operation \*\*Condition\*\* New Old Stock – \*\*NOS\*\* – never installed or used.
