Deer Pay Attention to Hi-Lo
Wolo® - 2 Trumpet Chrome Super Loud Air Horn with Heavy Duty Compressor
Wolo 416 kit complaints: instructions say to use 16ga wire, wire included in kit is 18ga, connectors in kit are 18ga. 20A fuse in kit is for 16ga and unsuitable to protect 18ga, insulated connector for side tab terminal of compressor (that instructions mention as important to use) does not fit into tab space. Wiring diagram does not mention that hi-lo_vs_both switch relies on case ground through mount point, and does not/cannot ground through ground tab on compressor end. I love the sound of this horn, and the ability to switch to a steady combined tone in town. Unfortunately, the quality control of the components doesn't seem great. Wolo does have phone tech support, but that conversation was not hugely helpful to us. My mechanic persuaded this Dec 2019 purchase (replacing a misbehaving much older Wolo 416 model) to work, so I can once again shoo deer off the road. Thanks for price matching.
