The Indicator Stalk, a critical component of your vehicle’s turning signal system, allows you to signal your intention to turn or change lanes. A malfunctioning indicator stalk can be a safety hazard, making it crucial to understand its operation and how to address common issues. This article will delve into the mechanics of a common indicator stalk failure and outline a successful repair process.
Common Indicator Stalk Issues: A Case Study
A common problem with indicator stalks, particularly in classic cars like the TR6, Spitfire, and TVR Vixen, involves the failure of a small rivet holding the self-cancelling mechanism. This mechanism ensures the indicator stalk returns to its neutral position after completing a turn. When this rivet fails, the stalk may become loose or unable to hold its position when signaling a turn.
In one instance, a vehicle owner experienced a recurring issue with the indicator stalk not staying in the “up/left turn” position. Upon disassembly, the rivet responsible for the self-cancelling ear was found to be detached, although all the associated components were miraculously still present. After reassembling the stalk and reinforcing the rivet with adhesive, the problem persisted.
Diagnosing and Fixing the Problem
Further inspection revealed that the issue stemmed from the interaction between the plastic cam, which pivots with stalk movement, and the small U-shaped sprung metal clips on either side. The cam’s lugs were not engaging properly with the U-bend of the clips, preventing the stalk from remaining in the signaled position.
The solution involved carefully removing the sprung metal clips and slightly reshaping them with pliers to create a more open angle in the U-bend. This adjustment allowed the clips to securely engage with the cam lugs, effectively holding the indicator stalk in the desired position.
Conclusion
This simple repair saved the vehicle owner the cost of a new indicator stalk assembly. By understanding the mechanics of the indicator stalk and employing careful diagnostic techniques, it’s often possible to rectify common problems without resorting to expensive replacements. Regular inspection and maintenance of your indicator stalk can contribute to safer driving and prolonged vehicle lifespan.
