Not tried a Thermal Camera for that, but have recently bought a FLIR-One for Android ... cheap enough to start having a play, and with our dual banks/cats can help identify issues with cat performance/imbalance (temp) and individual manifold branches, thermostat housing failure through to interior heater vent output issues ... all recent work that could have been easier to identify and certainly clearer communicate to the client with images to support the diagnosis ... so we got one! It is really good, should have bought one years ago, but glad we now have it. Maybe I should play with it more!
How do you use it for Parasitic drain?
Our drains are typically 100-250ma excess draw so not massive, sometimes more, often less @ only 40ma excessive but not many verse the volume of these 100-250! (so 150-300ma total drain)
In fact we have 5 cars on site with small drains
- 3 all at 260 - 280ma
- 1 with 670ma
- 1 with 380ma
Odd yes, but I guess end of winter hibernation for many of our owners! Things happen while in storage (moisture mainly!). Only 1 came in for the issue, but we check all cars as part of our health check along with battery/starter/alternator - trainee's learn by repetition, so they get to do every car! Helps familiarity with the scope, so they can set it up with complete confidence, helps when they are asked to do something more difficult as the basics are well ingrained.
We don't use the scope for parasitic drain initial testing, as the time to do it is too long, and while the para test is running they can setup the starter/battery tests, rather than twiddle their fingers. We use "The Hook" for the initial drain test, can be setup in under 1 minute, even if a earth has to be manually disconnected, all without loss of ECU memory.
I'm thinking that using the thermal camera on the fuses themselves (the fine blowable strip?) but I think the camera we have would read the shell temp as it does with glass, rather than what's inside/behind it? How else do you use it?
I'm really interested to add a new methodology to the proverbial tool chest ...
Please spill the beans!
