PHANTOM III & WRAITH ------------------------------------- We observed on chassis 3.DL.58 and WXA.11 that the copper contacts of the fuse holders had overheated and were in a black condition. The above fuse holders take the B.2 open type fuses which protects the dynamo circuit. We observed that the contacts or clips of the fuse holders did not have enough "pinch" and this we think caused them to overheat. It would appear to us that stronger contact clips would be an advantage. Sr/VA. | ||
