[TR] Was TR3a Smith's heater fan ground wire

[auprichard uprichard.net]

I normally test them to about 7 or 8 psi (I realize they should not see more than 4, but I like the comfort zone).  If they hold pressure and look good, I will use them. Failing that, I find it best to go find another or buy new.  From what I have heard, they are extremely difficult to repair and prone to future problems.  And, unlike a radiator leak, a leaking heater core (a) is a pain to replace and (b) will make a mess on what are frequently nice new carpets.

Regarding your question about the fan, the radiator people I know only like to deal with plumbing.  On the other hand, being a cardiologist, I can tinker with plumbing AND electricity – but patients were so much easier than Triumphs……….

Has anyone taken their TR3 heater to a radiator shop to recorded and rebuilt? Will they touch the fan portion or just deal with the core itself?

Thanks!!

I wish all of my problems were that easy to resolve.

Good job!

Well that was almost too easy.   Turns out when I replaced the heater hoses last year I neglected to even re-attach the ground wire, it must have been lying against a convenient ground right up until last week.

Any idea where it should be?   Fan stopped working soon after the OEM reostat failed (replaced by simple toggle) which was soon after one of the heater hoses cracked at the core side.    I'm assuming it's the fan that's shot but I'm willing to place a long shot bet on the ground wire before I tackle that job again.

Thanks,
