X.3445 - IGNITION COIL NO.3855 EX CHASSIS GF.23 -BILLSON- From the result of our test, this coil apparently has an incipient fault, which is not always in evidence. As stated in my assistant's report WA.{Mr Wallis}47, copy of which we attach, it is recommended that the coil be carefully unwound to ascertain the exact nature and location of the fault. We return the coil herewith. EFC. [Faint stamp in center] 4081 | ||
