electrical hum

[tj500]

Done it! After many years of longing, finally acquired my dream machine, 97 Griff 500 Ocean Haze. (Actually I 'did'it' 2 months ago but have been too busy blasting around having fun to sign up & share my joy with the ph community). It's everything & more I hoped for. So far have completed around 900 miles of completely niggle-free fun & giggles.

Am based in Spain, where I bought the car, & since there is nothing resembling an official (or unofficial) TVR service outpost here, will be bringing the beast over to the UK this month for a full service, the first longish trip to be undertaken. Taking all reasonable precautions I can think of (for which there's much useful info from previous posts on ph) but had one little doubt I've been unable to get any info on from earlier threads, or from the bible. Turning on the ignition, there are two principal sounds: i) fuel pump, lasting about 3 seconds; ii) electrical hum from the battery area, which does not disappear once engine is running (although once running you can't hear it unless you put your ear very close to the battery area). What is it & is it normal? Would appreciate any feedback.

PS Any other Spain-based Griff/TVR owners?

Thanx for feedback. It's not ventilation fan, that's more of a whirr than a hum & seems to function fine. Sounds highly likely davidn's put his finger on pulse with heater valve motor diagnosis. I will investigate....
